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.

Question

Philoid · Accepted Answer

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
