Home » Aptitude » Mensuration » Question

The radius of a sphere and right circular cylinder is ‘r’ units. Their volumes are equal. The ratio of the height and radius of the cylinder is :

1. 3 : 1
2. 2 : 1
3. 3 : 2
4. 4 : 3

Correct Option: D

Volume of sphere = Volume of cylinder

⇒	4	πr³ = πr²h
	3

⇒ 4r = 3h

⇒	h	=	4	= 4 : 3
	r		3
