Let the radii of the two cylinders be 2r and 3r respectively.
And the length of the two cylinders be 5h and 3h respectively.
Now, Ratio of the lateral surface area or curved surface area of the two cylinders
= 2π (2r)( 5h)/ 2π (3r)(3h)
= 10/9
Therefore, the lateral surface areas of the two cylinders are in the ratio 10 : 9
