Answer:

They used 3.14 for pi:

$V=(4)/(3) \pi r^3$

V=(4)/(3) (3.14)(5)^3

Explanation:

$V=(4)/(3)\pi r^3$ is the volume of a sphere with radius r.

I think that is the diameter given in the picture.

The radius is half the diameter.

So the radius is 5 since the diameter is 10.

Plug in this gives you:

$V=(4)/(3) \pi (5)^3$
