Answer :

__Given__ : Ratio of radii of two cylinders = r_{1} : r_{2} = 3 : 2

Ratio of heights of the two cylinders = h_{1} : h_{2} = 5 : 3

__To find__ : Ratio of CSA of the two cylinders = C_{1} : C_{2} = ?

__Formula__ : CSA of cylinder = 2rh

__Solution__ : CSA of first cylinder = C_{1} = 2r_{1}h_{1}

CSA of first cylinder = C_{2} = 2r_{2}h_{2}

∴

⇒

∴ C_{1} : C_{2} = 5 : 2

∴ The ratio of the curved surface areas of the two cylinders is 5 : 2.
