Question

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

Answer 1

Answer:

135 ft^3

Step-by-step explanation:

The volume of a cone is $\frac{1}{3} \pi r^{2}h$. The radius is 4 and the height is 8, so these values can be plugged in:

$V = \frac{1}{3} \pi \times 4^{2} \times 8$

$V = \frac{128\pi }{3}$

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