Question

the radii of two cylinder are in the ratio 2:3 and their heights are in the ratio 5:3 . Calculate the ratio of their curved surface area​

Answer 1

Step-by-step explanation:

let radius of the cylinder is 2X and 3 X.

As same height as 5Y and 3Y.

now simply find the ratio...

2π(2X)(5Y) : 2π(3X)(3Y)

= (2X)(5Y) : (3X)(3Y)

= 10 : 9
