Question

A sphere and a cylinder have the same radius and height the volume of the cylinder is 48cm what is the volume of the sphere

Answer 1

Explanation:

Since they have the same height, the h of the cylinder must be 2r like the sphere.

`V_c=h\pi r^2,\ given\ h=2r,\ V_c=2\pi r^3,\ 2\pi r^3=48,\ r^3=(24)/(\pi)\\ \\ V_s=(4\pi r^3)/(3),\ V_s=32 cm^3`
