Question

Find the volume of a right circular cone that has a height of 18.6 m and a base with a radius of 15.5 m. Round your answer to the nearest tenth of a cubic meter.

Answer 1

This one should have come before the other one. We apply the cone formula

$V = \frac 1 3 \pi r^2 h$

$V = \frac 1 3 \pi(15.5)^2 (18.6) \approx 4679.6 \textrm{ cubic meters}$
