Answer 2

Answer:

Correct option is

D

20:27

As radii of two cylinder in in ratio of 2:3

So radius of 1st cylinder=2r

radius of 2st cylinder=3r

heights are in the ratio 5:3.

height of 1st cylinder=5h

height of 2st cylinder=3h

ratio of volume=volume of 1st cylinder/volume of 2nd cylinder

V=Π(2r)

2

∗5h/Π(3r)

2

∗3h

V=20rh/27rh

V=20/27
