Find the volume of a right circular cone that has a height of 4.5 ft and a base with a
diameter of 14.2 ft. Round your answer to the nearest tenth of a cubic foot.
Answers
Answer:
The volume of the cone is:
237.6 cubic feet.Step-by-step explanation:
The volume of a cone is:
Volume of a cone = (1/3) PI * r^2 * hWhere:
r = radius.
h = height.
Since the exercise provides the diameter but not the radius, you simply have to divide the diameter in two:
Radius = diameter / 2 Radius = 14.2 ft / 2 Radius = 7.1 ft / 2Now we proceed to replace in the formula:
Cone volume = (1/3) PI * (7.1 ft)^2 * 4.5 ft Cone volume = 237.5515285 ft^3 Cone volume = 237.6 ft^3Related Questions

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.

For the following data, find
a. Mean
b. Median
c. Mode
d. Range
e. Interquartile range
f. Another value that will make the mean 16.875
g. Another value that will not change the median
You must show all of your work to receive credit.
Answers
Answer:
f. age=16
g. age=17
Step-by-step explanation:
f. Mean is the sum of all the ages divided by the number of people. You need to make sure to account for the frequency of each age as well. Let x represent the other value that will make the mean 16.875. The number of people is sum of all the frequency values, plus one because you're adding a value (x).
mean=16.875= (12+13+14*3+15*3+16*2+17*3+18*5+19+20+21+22*2+x)/(1+1+3+3+2+3+5+1+1+1+2+1)
if you simplify that whole thing, you should get:
16.875=(x+389)/24
Now you need to solve for x.
Multiplying by 24 on both sides:
x+389=405
subtract 389 from both sides to get
x=16
That's the last value you need to add, another person who got their first job at 16.
g. If you listed all the ages out, making sure to account for the frequency of each age, the median would be the middle value, the one in the very center. Let's find it. Here's a complete list of all the ages:
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
It's pretty boring, but what you do next is you cross values off from either end until you reach the center. (I'll use underline to show you because there is no strikethrough.)
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
and so on, until you have:
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
The median is 17 because it's the value at the very middle. If you were to add a value without changing the median, it would have to be 17. Let's look at what would happen then.
12, 13, 14, 14, 14, 15, 15, 15, 16, 16, 17, 17, 17, 17, 18, 18, 18, 18, 18, 19, 20, 21, 22, 22
You would have 2 values at the center instead of just one, because there's an even number of values now. To find the median, you have to find the mean of the two remaining points. The mean is (17+17)/2, which is just 17.
Hope this helps!

The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.

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.
