The circumference of the cylinder below is 6 cm and the height is 8 cm. What is the curved surface area of the cylinder? If your answer is a decimal, give it to 1 d.p. circumference = 6 cm
8 cm
The curved surface area of the cylinder is 48.06 cm².
The circumference of a cylinder is given by the formula:
C = 2πr
where C is the circumference and r is the radius of the base.
In this case, the given circumference is 6 cm.
So, 6 = 2πr
r = 6 / (2π)
r ≈ 0.955 cm
Now, the curved surface area (CSA) of the cylinder using the formula:
CSA = 2πrh
Given the height as 8 cm, we can substitute the values into the formula:
CSA = 2π(0.955 cm)(8 cm)
CSA ≈ 48.06 cm²
Therefore, the curved surface area of the cylinder is 48.06 cm².

What is the measure (in radians) of central angle \thetaθtheta in the circle below?
Answer: 2.5 radians
Step-by-step explanation: Khan Academy
The measure of the central angle is 2.5 radians in the circle below.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The arc length of a circle is 5 cm.
And the radius is 2 cm.
And we know,
Length of an Arc = θ × r,
where θ is in radian.
Substituting the values of arc and radius.
5 = θ × 2
Rearranging,
The angle measure θ = 5/2
θ = 2.5 radians.

Graph the given function and choose the key features that apply to its graph.
f(x)=-3x+2
Answer:
The graph has a y- intercept at(0,1) and is decreasing over the interval -infinity <x< infinity
Step-by-step explanation:
Trust me
To graph the function f(x) = -3x + 2, we can plot some points and then connect them to form a straight line.
Here are a few points you can use to plot the graph:
1. When x = 0, f(0) = -3(0) + 2 = 2. So, the point (0, 2) is on the graph.
2. When x = 1, f(1) = -3(1) + 2 = -1. So, the point (1, -1) is on the graph.
3. When x = -1, f(-1) = -3(-1) + 2 = 5. So, the point (-1, 5) is on the graph.
Plot these points on a coordinate plane and then draw a straight line passing through them. The graph should be a straight line sloping downwards from left to right.
Key features of the graph:
1. Slope: The slope of the line is -3, which means it goes down 3 units for every 1 unit it moves to the right.
2. Y-intercept: The y-intercept is the point where the graph crosses the y-axis. In this case, the y-intercept is 2, as the graph passes through the point (0, 2).
3. X-intercept: The x-intercept is the point where the graph crosses the x-axis. To find the x-intercept, set f(x) = 0 and solve for x:
0 = -3x + 2
3x = 2
x = 2/3. So, the x-intercept is approximately (2/3, 0).
4. Linearity: The graph is a straight line, indicating that the function is a linear function.
5. Decreasing: The graph decreases as you move from left to right, indicating that the function is a decreasing function.

The perimeter and area of a rectangle are 22 cm
and 30 cm² respectively. Find the length and
breadth of the rectangle
The perimeter and area of a rectangle are (5,6) and (6,5).
The perimeter method for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents length, and W represents width. when you are given the size of a square form, you may simply plug within the values of L and W into the formula that allows you to clear up for the fringe.
A perimeter is a closed course that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional period. The perimeter of a circle or an ellipse is known as its circumference. Calculating the perimeter has several practical programs.
The perimeter P of a rectangle is given by means of the method, P=2l+2w, in which l is the period and w is the width of the rectangle. The place A of a rectangle is given with the aid of the components, A=lw, wherein l is the length and w is the width.
The perimeter of the rectangle:
P=2l+2w=22
divide 2 into both sides
l+w=11 -------------> (1)
w=11-l
Area of the rectangle:
l*w=30
l(11-l)=30
11l-l^2-30=0
l^2-11l+30=0
By factor method,
(l-5)(l-6)=0
l=5,6.
Substitute this value in w,
l=5 implies w=6
l=6 implies w=5
There we have two solutions.

Answer:
third option
Step-by-step explanation:
Given the following formula, solve for a.
s=a+b+c/2
We can rearrange it to the standard form perimeter a = s - b - C/2
In arithmetic, what is a perimeter?
The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
The answer to your question is a = s - b - C/2
To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:
0 = a + b + C/2 - s
Then, we can subtract a from both sides:
-a = b + C/2 - s
Finally, we divide both sides by -1, so a is by itself.
a = -b - C/2 + s
And we can rearrange it to the standard form:
a = s - b - C/2

There are 99 books stacked on a shelf. The thickness of each book is either 11 inch or 22 inches. The height of the stack of 99 books is 1414 inches. Which system of equations can be used to determine xx , the number of 11-inch-thick books in the stack, and yy , the number of 22-inch-thick books?F. x+y=14x+2y=9x+y=14x+2y=9 G. x+y=92x+y=14x+y=92x+y=14 H. x+y=9x+2y=14x+y=9x+2y=14 J. x+y=142x+y=9x+y=142x+y=9
Given that:
the number of 1-inch thick books = x
the number of 2-inch thick books= y
Total number of stacked books = 9
The height of the stacked books = 14 inches
First equation:
Since the total number of stacked books is 9, the addition of the 1-inch thick books and 2-inch thick books must equal 9.
That is,
\(x+y=9\)Second equation
The height of the stack of books is 14
The height of the 1-inch books =
\(1\text{ }\times x\text{ = }x\)The height of the 2-inch books =
\(2\text{ }\times y\text{ =2}y\text{ }\)Since the total height of the stacked books is 14, the addition of the height of the 1-inch and 2-inch books must be 14.
That is,

0 is an angle in a right-angled triangle. tan 0 = 23/52 What is the value of 0? Give your answer in degrees to 1 d.p.
The value of the angle θ is approximately 24.2 degrees to 1 decimal place.
In a right-angled triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Given that tan θ = 23/52, we can find the value of the angle θ.
To find the value of θ, we can use the inverse tangent or arctan function. Taking the inverse tangent of both sides of the equation, we have:
θ = arctan(23/52)
Using a calculator or trigonometric tables, we can evaluate the inverse tangent of 23/52. The result is approximately 24.2 degrees.
Note that in the context of a right-angled triangle, the tangent function is defined for acute angles (less than 90 degrees). Since 0 degrees is the smallest possible angle, it is considered an acute angle in this case.

If f ' is continuous, f(5) = 0, and f '(5) = 7, evaluate
lim x→0
f(5 + 5x) + f(5 + 6x)

Correct question is;
If f ' is continuous, f(5) = 0, and f '(5) = 7, evaluate;
lim x→0 [f(5 + 5x) + f(5 + 6x)]/x
Answer:
The limit is 77
Step-by-step explanation:
Since we want to evaluate;
lim x→0 [f(5 + 5x) + f(5 + 6x)]/x
Thus, let's plug in 0 for x to get;
lim x→0 [f(5 + 5x) + f(5 + 6x)]/x = [f(5) + f(5)]/0
Since we are told that f(5) = 0, thus we now have;
[f(5) + f(5)]/0 = 0/0
Since, we have a limit of both numerator and denominator as 0,thus let's apply L'Hospital's Rule which states that: if we have an indeterminate form of 0/0 or ∞/∞, we will differentiate the numerator and differentiate the denominator and then take the limit.
Thus, applying L'Hospital's rule and using chain rule in differentiating, we have;
lim x→0 [5f'(5 + 5x) + 6f'(5 + 6x)]/1 = 5f'(5) + 6f'(5) = 11f'(5)
We are given f'(5) = 7
Thus,we now have;
11 × 7 = 77
An indeterminate form is an expression involving two functions whose limit cannot be determined solely from the limits of the individual functions.
After evaluation, \(\lim_{x \to 0} \frac{f(5+5x)+f(5+6x)}{x} =77\)
Here, given that, f(5) = 0, and f '(5) = 7
We have to find,
\(\lim_{x \to 0} \frac{f(5+5x)+f(5+6x)}{x}\)
When substituting the limit x=0. We get 0/0 form which is indeterminate form.
So, Here we use L'Hospital's rule, because direct substitution of a limit yields an indeterminate form.
\(\lim_{x \to 0} \frac{5*f'(5+5x)+6*f'(5+6x)}{1} =\frac{5f'(5)+6f'(5)}{1}\)
Substituting the value of f '(5) = 7 in above equation.
\(=\frac{5f'(5)+6f'(5)}{1}=\frac{(5*7)+(6*7)}{1}\)
= \(35+42=77\)
Thus, \(\lim_{x \to 0} \frac{f(5+5x)+f(5+6x)}{x} =77\)

What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
The outcomes for each of the following events are:
(a) Event "X and Y": {C}
To satisfy both events X and Y, the letter selected must come before "D" (which includes the letters A, B, and C) and must be one of the letters in the word "CAGE" (which includes only the letter C). Therefore, the only outcome that satisfies both events X and Y is the letter C.
(b) Event "X or Y": {A, B, C, E, G}
The outcomes that satisfy event X are A, B, and C (since they come before "D"), and the outcomes that satisfy event Y are C, A, G, and E (since they are letters found in the word "CAGE"). Therefore, the outcomes that satisfy either event X or event Y are {A, B, C, E, G}.
(c) The complement of event X: {D, E, F, G}
The complement of event X is the set of outcomes that do not satisfy event X. The outcomes that do not satisfy event X are D, E, F, and G (since they come after or are equal to "D"). Therefore, the complement of event X is {D, E, F, G}.
