ICE Princess25 [194]

Which expression can be used to find the volume of the sphere?
Kryger [21]

Answer:

They used 3.14 for pi:

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} (3.14)(5)^3

Step-by-step explanation:

V=\frac{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=\frac{4}{3} \pi (5)^3
