Find the volume $V$ of a sphere if radius $r = 4 cm$ .

Answer

$\frac{256}{3} π cm^{3}$

Explanation

To find volume $V$ use formula:

V = \frac{4 \cdot r ^{3} \cdot π}{3}

After substituting $r = 4 cm$ we have:

V = \frac{4 \cdot ( 4 cm ) ^{3} \cdot π}{3}

V = \frac{4 \cdot 64 cm ^{3} \cdot π}{3}

V = \frac{256 cm ^{3} \cdot π}{3}

V = \frac{256}{3} cm^{3} \cdot π
