Solve the Problem $r = \sqrt { \frac { 3 V } { \pi h } }$

Multiple Choice

Solve the problem.
-For a cone, the formula $r = \sqrt { \frac { 3 V } { \pi h } }$ describes the relationship between the radius $r$ of the base, the volume $V$ , and the height h. Find the volume if the radius is 8 inches and the cone is 6 inches high. (Use $3.14$ as an approximation for $\pi$ , and round to the nearest tenth.)

A) $401.9$ cubic in.
B) $50.2$ cubic in.
C) $3617.3$ cubic in.
