Question

The radii of two cylinders are in the ratio 2:3 and their heights are in the
ratio 5 : 3. Calculate the ratio of their volumes and the ratio of their
curved surfaces.
​

Answer 1

Step-by-step explanation:

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

of second cylinder. V = Π(2r) *5 h/Π(3r) ^2 *3h

V= 20rh / 27rh

V = 20/27 .
