Question

Find the volume of a right circular cone that has a height of 9.7 ft and a base with a radius of 7.6 ft. Round your answer to the nearest tenth of a cubic foot.

Answer 1

586.7 ft^3

Explanation:

1) find the base area

base area = radius^2 x pi = 7.6^2 x pi = 181,458392 ft^2

2) find the volume

V = (base area x height)/3 = (181,458392 x 9.7)/3 = 586.7 ft^3
