Inverses and Radical Functions · Exercise 65

Determine the function described and then use it to answer the question.

The volume of a right circular cone, $V,$ in terms of its radius, $r,$ and its height, $h,$ is given by $V = \frac{1}{3} π r^{2} h .$ Express $r$ in terms of $V$ if the height of the cone is 12 inches and find the radius of a cone with volume of 50 cubic inches.
