Find the volume $V$ of a sphere if diameter $d = 19.2 cm$ .

Answer

$1179.648 π cm^{3}$

Explanation

STEP 1: find radius $r$

To find radius $r$ use formula:

d = 2 \cdot r

After substituting $d = 19.2 cm$ we have:

19.2 cm = 2 \cdot r

r = \frac{19.2 cm}{2}

r = 9.6 cm

STEP 2: find volume $V$

To find volume $V$ use formula:

V = \frac{4 \cdot r ^{3} \cdot π}{3}

After substituting $r = 9.6 cm$ we have:

V = \frac{4 \cdot ( 9.6 cm ) ^{3} \cdot π}{3}

V = \frac{4 \cdot 884.736 cm ^{3} \cdot π}{3}

V = \frac{3538.944 cm ^{3} \cdot π}{3}

V = 1179.648 cm^{3} \cdot π
