Calculate the volume of a sphere with the following radius:

$36\pi$

CORRECT

$24\pi$

$16 \pi$

$8\pi$

$33\pi$

We can calculate the the volume of a sphere using the following formula:

$V=\frac{4}{3}\pi r^3$

in this formula the variable, , represents the radius of the sphere.

Substitute in the known radius and calculate the volume.

$V=\frac{4}{3}\times \pi \times 3^3$

$V=\frac{4}{3}\times \pi \times 27$

$V=\frac{4}{3}\times 27\pi$

Simplify.

$V=\frac{4}{3}\times \frac{27\pi}{1}$

$V=\frac{108\pi}{3}$

Solve.

$V=36\pi$
