## anonymous 5 years ago A sphere has a volume of 972π in.3. Find its radius.

Hikari, you need to use the formula for the volume of a sphere:$V=\frac{4}{3}\pi r^3$You have the volume given to you already, so all you need to do is rearrange that formula to find the radius:$r=\sqrt[3]{\frac{3V}{4 \pi}}=\sqrt[3]{\frac{3\times 972 \pi}{4 \pi}}=\sqrt[3]{729}=9$So the radius is 9 inches.
