Find the volume $V$ of a sphere if diameter $d = 100 cm$ .

Answer

$\frac{500000}{3} π cm^{3}$

Explanation

STEP 1: find radius $r$

To find radius $r$ use formula:

d = 2 \cdot r

After substituting $d = 100 cm$ we have:

100 cm = 2 \cdot r

r = \frac{100 cm}{2}

r = 50 cm

STEP 2: find volume $V$

To find volume $V$ use formula:

V = \frac{4 \cdot r ^{3} \cdot π}{3}

After substituting $r = 50 cm$ we have:

V = \frac{4 \cdot ( 50 cm ) ^{3} \cdot π}{3}

V = \frac{4 \cdot 125000 cm ^{3} \cdot π}{3}

V = \frac{500000 cm ^{3} \cdot π}{3}

V = \frac{500000}{3} cm^{3} \cdot π
