Question

Find the volume (to the nearest cubic foot) of a cone with base radius 4 ft. and height 8 ft.

Answer 1

135 ft^3

Explanation:

The volume of a cone is
`(1)/(3) \pi r^(2)h`. The radius is 4 and the height is 8, so these values can be plugged in:

`V = (1)/(3) \pi * 4^(2) * 8`

`V = (128\pi )/(3)`

This is about 134.041286553 which rounds to 135 ft^3.
