$\begin{array}{r} r = & 8 cm \end{array}$

Step 1

The volume of a sphere is equal to

$\frac{4}{3}$ times Pi

$π$ times the radius cubed.

$\frac{4}{3} \cdot π \cdot {(r a d i u s)}^{3}$

Step 2

Substitute the value of the radius

$r = 8$ into the formula to find the volume of the sphere. Pi

$π$ is approximately equal to

$3.14$ .

$\frac{4}{3} \cdot π \cdot 8^{3}$

Step 3

Combine

$\frac{4}{3}$ and

$π$ .

$\frac{4 π}{3} \cdot 8^{3}$

Step 4

Raise

$8$ to the power of

$3$ .

$\frac{4 π}{3} \cdot 512$

Step 5

Multiply

$\frac{4 π}{3} \cdot 512$ .

Step 5.1

Combine

$\frac{4 π}{3}$ and

$512$ .

$\frac{4 π \cdot 512}{3}$

Step 5.2

Multiply

$512$ by

$4$ .

$\frac{2048 π}{3}$

$\frac{2048 π}{3} {(cm)}^{3}$
