A sphere has a volume of 4500pi cubic inches. find the surface area of the sphere.
MakcuM [25]
V=\frac{4 \pi r^3}{3}\\

4500\pi=\frac{4 \pi r^3}{3}\\
\\
13500 \pi=4 \pi r^3\\
\\
r^3=\frac{13500 \pi}{4 \pi}\\
\\
r^3=3375 \\
\\
\boxed{r=15 in}

S=4 \pi r^2\\
\\
S=4 \pi 15^2\\
\\
\boxed{S=900 \pi \ in^2}
