Answer:
Step-by-step explanation:
Radii=2:3
Height=5:8
Curved surface area of cylinder=2πrh
2πrh : 2πRH(where r,R,h,H are the radii and heights of the two cylinders)
rh : RH(since 2π gets cut on both sides)
Let the radii and heights be in the ratio of k, then,
2k×5k : 3k×8k
10k square : 24k square
10k square/24k square= 5/8
Thus, ratio of curved surface areas of 2 cylinders is 5:8.
