The radius of a right circular cone is given by the formula $r=\sqrt{\frac{3 V}{\pi h}}$, where $V$ is the volume and $h$ is the height. If the volume is 1302 cubic inches and the height is 14 inches, what is the radius? Use 3.14 for $\pi$, and round your answer to the nearest tenth of an inch.
A) 0.1 inches
B) 5.4 inches
C) 9.9 inches
D) 9.4 inches

Substitute $V = 1302$ and $h = 14$ into the formula: $r = \sqrt{\frac{3 \times 1302}{3.14 \times 14}}$. Calculate the value to find $r \approx 9.4$ inches.
