Find the Volume sphere (15cm)

 $\begin{array}{r} r = & 15 cm \end{array}$

The volume of a sphere is equal to $\frac{4}{3}$ times Pi $π$ times the radius cubed.

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

Substitute the value of the radius $r = 15$ into the formula to find the volume of the sphere. Pi $π$ is approximately equal to $3.14$ .

$\frac{4}{3} \cdot π \cdot 15^{3}$

Combine $\frac{4}{3}$ and $π$ .

$\frac{4 π}{3} \cdot 15^{3}$

Raise $15$ to the power of $3$ .

$\frac{4 π}{3} \cdot 3375$

Cancel the common factor of $3$ .

Factor $3$ out of $3375$ .

$\frac{4 π}{3} \cdot (3 (1125))$

Cancel the common factor.

$\frac{4 π}{3} \cdot (3 \cdot 1125)$

Rewrite the expression.

$4 π \cdot 1125$

Multiply $1125$ by $4$ .

$4500 π {(cm)}^{3}$
