 $\begin{array}{r} r = & 3.9 \end{array}$

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 $r = 3.9$ into the formula to find the volume of the sphere. Pi $π$ is approximately equal to $3.14$ .

$\frac{4}{3} \cdot π \cdot {3.9}^{3}$

Step 3

Combine $\frac{4}{3}$ and $π$ .

$\frac{4 π}{3} \cdot {3.9}^{3}$

Step 4

Raise $3.9$ to the power of $3$ .

$\frac{4 π}{3} \cdot 59.319$

Step 5

Multiply $\frac{4 π}{3} \cdot 59.319$ .
