Question

What is the volume of the cone with radius 4 ft and height 10 ft? Round to the nearest cubic foot.

A) 126 ft3


B) 200 ft3


C) 251 ft3


D) 168 ft3

Answer 1

D) 168 ft3

Explanation:

The formula to find the volume of a cone is V=π
`r^(2)`
`(h)/(3)`.

We need to plug in the radius, 4, and the height, 10, into this equation.

V=π
`(4)^(2)`
`(10)/(3)`

V=π16
`(10)/(3)`

V=π53.33

V=167.55

If we round up to the nearest whole number, we get 168
`ft^(3)`. Therefore, the correct answer is D) 168 ft3.
