Question

Find the volume for each figure. Use 3.14 for Pi
1.
r=21 ft-
35 ft

Answer 1

V = 16155.3 cubic feet

Explanation:

The formula for volume (V) of a cone is

`V=1/3\pi r^2h`, where r is the radius and h in the height.

In the diagram, we're shown that the radius is 21 feet and the height is 35 feet. Thus, we can plug everything into the formula including 3.14 instead of the entire pi number:

`V=1/3(3.14)(21)^2(35)\\V=16155.3`
