Answer 2

Answer:

Let the radius of the sphere and cylinder be r.

Given, height of the cylinder = diamter of the bases

⇒ h=2r

According to the given condition,

Volume of sphere =23× volume of cylinder

⇒ 43πr3 =23×πr2×2r

⇒ 43πr3 =43πr3

Hence, the volume of a sphere is equal to two-third of the volume of a cylinder.
