Q7 of 62 Page 22

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 curved surface areas.

Given,


Ratio of radius of two cylinder = 2:3


Ratio of their heights = 5:3


=


So,


=


Hence,


Ratio of their curved surface area would be = 10 : 9
