Question

The radii of two right circular cylinder are in the ratio 2:3 and their heights are in the ratio 5:4. calculate the ratio of their curved surface area. ​

Answer 1

Here is your Answer.



Ratio of radii = Let and Ratio of heights = Let and CSA of the first cylinder = 2πrh = CSA of the second cylinder = 2πRH = = Ratio of their CSA = Hence the ratio of the volumes of cylinders is 5:6 Volume of the first cylinder = πr2h = = Volume of the second cylinder = πR2H = = Ratio of their Volume = Hence the ratio of the volumes of cylinders is 5:9

I hope my answer is help you.
