What is the area of the base of the cone below? Round the answer to the nearest tenth if necessary.

A cone with height 8 inches and volume 52 inches cubed.
14.7 inches squared
17.3 inches squared
18.5 inches squared
19.5 inches squared

1 answer

The formula for the volume of a cone is V = (1/3) * π * r^2 * h, where r is the radius of the base and h is the height.

Given that the volume is 52 inches cubed and the height is 8 inches:
52 = (1/3) * π * r^2 * 8
r^2 = 52 / ((1/3) * π * 8)
r^2 ≈ 2.083

Now we need to find the area of the base of the cone using the formula A = π * r^2:
A = π * 2.083
A ≈ 6.55 inches squared

Therefore, the closest option is 14.7 inches squared when rounded to the nearest tenth.
