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 curved surface areas​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

let the radii be 2x and 3x

let the height be 5x and 3x

fot first cylinder

curved surface area=2πrh

=2π2x*5x/2π3x*3x

=10x/9x

=10/9

=10:9
