Question

Find the volume of the cone. r = 9 in. h = 3 in. (1st do normal then 2nd answer should be rounded to the nearest hundred)

Answer 1

The volume of cone is V = 1/3 π r² h

Plug in r = 9 and h = 3:

1/3 π (9)² (3) = 81π

So volume is 81π in³

Rounding to neatest hundredth: 254.47 in³
(If you actually want nearest hundred then 300 in³)
