# What is the volume of the sphere? Use 3.14 to approximate pi. Enter your answer in the box. Round to the nearest tenth.

$\bf \textit{volume of a sphere}\\\\ V=\cfrac{4}{3}\pi r^3\qquad r=3\implies V=\cfrac{4}{3}\pi 3^3 \\\\\\ V=\cfrac{4\pi 3\cdot 3\cdot 3}{3}\implies V=4\pi \cdot 3\cdot 3\implies V=36\pi \ ft^3$
