Question

Find the volume of a right circular cone that has a height of 4.5ft and a base with a diameter of 14.2 feet. Round your answer to the nearest tenth of a cubic foot.

Answer 1

The volume of a cone with height h and radius r (half of it's diameter) is v = pi*h*r^2/3

For h = 4.5 ft and r = 14.2/2 = 7.1 ft, we have:

v = pi*4.5*(7.1^2)/3 = 237.6 ft^3
