the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answers
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards, you can set up the equation:
144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6
Thus, the radius of the base of the cylinder is 6 yards.
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Ricardo’s goal was to run 40 laps. At the end of the week, he ran 125% of his goal. How many laps is that?
Answers
Answer: He ran 50 laps.
Step-by-step explanation:
40 x 1.25 = 50
Answer:
50
Step-by-step explanation:
40/1 = 100/1
125% = 100/100 + 25/100
25% of 40 = 10
so you have the 40 laps which equal 100% and you also have 25 percent of the from the 125% and 25 percent of 40 is 10 so the answer is 40 plus 10 wich is 50
