Answer 1

Hi MP bro!!


Here is yr answer
_______________________________


Given,

Ratio of the radii of two cylinders = 2:3

R:r = 2:3


Ratio of the heights of two cylinders = 5:3

H:h = 5:3


Ratio of their lateral surface area = ??


Lateral surface are of cylinder = 2πrh

Ratio of the LSA of two cylinders = 2πRH : 2πrh

= RH : rh

= 2×5 : 3×3

= 10:9



Therefore, the ratio of the LSA of the two cylinders = 10:9



Hope it hlpz bro.....!!

Answer 2

❀ HERE IS YOUR ANSWER ❀

_______________________________


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
