 $\begin{array}{r} r = & 5.7 \end{array}$

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 $r = 5.7$ into the formula to find the volume of the sphere. Pi $π$ is approximately equal to $3.14$ .

$\frac{4}{3} \cdot π \cdot {5.7}^{3}$

Step 3

Combine $\frac{4}{3}$ and $π$ .

$\frac{4 π}{3} \cdot {5.7}^{3}$

Step 4

Raise $5.7$ to the power of $3$ .

$\frac{4 π}{3} \cdot 185.193$

Step 5

Multiply $\frac{4 π}{3} \cdot 185.193$ .

$\frac{4 π \cdot 185.193}{3}$

Step 5.2

Multiply $185.193$ by $4$ .

$\frac{740.772 π}{3}$

Step 5.3

Multiply $740.772$ by $π$ .

$\frac{2327.20387318}{3}$

Step 6

Divide $2327.20387318$ by $3$ .
