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 10 inches and the cone is 4 inches high. (Use $3.14$ as an approximation for $\pi$ , and round to the nearest tenth.)

A) $418.7$ cubic in.
B) $41.9 \mathrm { cubic }$ in.
C) $3768.0$ cubic in.
D) $104.7$ cubic in.
