Question

The radil 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.​

Answer 1

Answer:

u r total ratio is 15:10:9

Answer 2

Answer:

SolutionLet radii be 2r and 3r respectively

and height be 5h and 3h respectively

Volume ratio = Pi*(2r)^2 5h / Pi*(3r)^2 3h = 20:27

Curved surface area ratio = 2 Pi*(2r) 5h / 2 Pi*(3r) 3h = 10:9
