If a sphere of radius 2*r* has the same volume as that of a cone with circular base of radius *r*, then find the height of the cone.

Volume of a sphere = (4/3)πr^{3}

Volume of a right circular cone = (1/3)πr^{2}h

Given, a sphere of radius 2*r* has the same volume as that of a cone with circular base of radius *r*

⇒ h = 32r
