Check out the explanation.

The formula for the volume of a sphere is $V = \frac{4}{3} π r^{3}$ $V=4/3pir^3$

The diameter of the sphere is $12 c m$ $12 cm$ and the radius is half of the diameter, so the radius would be $6 c m$ $6 cm$ .

We're going to use $3.14$ $3.14$ for $π$ $pi$ or pi. So we now have:

$V = \frac{4}{3} \cdot 3.14 \cdot 6^{3}$ $V=4/3*3.14*6^3$

$6^{3}$ $6^3$ or $6$ $6$ cubed is $216$ $216$ . And $\frac{4}{3}$ $4/3$ is about $1.33$ $1.33$ .

$V = 1.33 \cdot 3.14 \cdot 216$ $V=1.33*3.14*216$

Multiply them all together and you get $\approx 902.06$ $~~902.06$ . You can always use more precise numbers!
