The diameter of the given sphere is 12cm.

we know that

$\text{Radius r }=(diameter)/(2)$

Substitute diameter=12cm, we get

$\text{Radius r =}\frac{12\operatorname{cm}}{2}=6\operatorname{cm}$

The volume of the sphere is

$V=(4)/(3)\pi r^3$
$\text{substitute }\pi=3\text{ and }r=6\text{ as follows.}$

$V\approx(4)/(3)*3*6^3$

$V\approx(4)/(3)*3*6*6*6$

Dividing 3 by 3 is 1.

$V\approx4*6*6*6$

Multiplying all the terms, we get the volume of the given sphere.

$V\approx864cm^3$
