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.

The volume $V$ of a cone can be found using the formula $V = \frac{1}{3} \pi r^2 h$. Given $r = 10$ inches and $h = 4$ inches, substituting these values into the formula gives $V = \frac{1}{3} \times 3.14 \times (10)^2 \times 4 = 418.7$ cubic inches.
