Find the volume $V$ of a sphere if radius $r = 6.4 cm$ and diameter $d = 12.8 cm$ .

Answer

$349.5253 π cm^{3}$

Explanation

To find volume $V$ use formula:

V = \frac{4 \cdot r ^{3} \cdot π}{3}

After substituting $r = 6.4 cm$ we have:

V = \frac{4 \cdot ( 6.4 cm ) ^{3} \cdot π}{3}

V = \frac{4 \cdot 262.144 cm ^{3} \cdot π}{3}

V = \frac{1048.576 cm ^{3} \cdot π}{3}

V = 349.5253 cm^{3} \cdot π
