If A denotes the volume of a right circular cylinder of same height as its diameter and B is the volume of a sphere of same radius, then A/B is :

1. 4/3
2. 3/2
3. 2/3
4. 3/4

Correct Option: B

Volume of cylinder = πr²h
⇒ A = πr² (2r) = 2πr³ [∵ h = 2r]

Volume of sphere =	4	πr³
	3

⇒	A	=	2πr³		=	6	=	3
	B		4	πr³		4		2
			3
