Answer:
The first cylinder radius =1
height =3
csa of cylinder =2πrh
=2×3.14×1×3
=18.84
The curved surface area of 1st cylinder =18.84
The second cylinder radius =3
height =2
csa of cylinder =2πrh
=2×3.14×3×2=37.68
The curved surface area of the 2nd cylinder =37.68
The ratio of their csa =18.84:37.68
