What is the volume of a sphere when r = 9 ft
volume of a sphere is calculated using a formula:\(\frac{4}{3} \pi * r^{3}\)so in this case:\(\frac{4}{3} \pi * 9^{3}\)and taht is:\(\frac{4}{3} \pi *729\)\(= 972 \pi\)Hope it helps you! :)
\(V=\frac43 \pi r^3\\ r=9m\\ \\ V=\frac43 \pi 9^3=\frac43 \cdot 729\pi=972\pi\)
