If the radii of two cylinders are in the ratio of 2 : 3 and their heights are in the ratio of 5 : 3, then the ratio of their volumes is:

22 : 15 20 : 27 3 : 4 16 : 23

20 : 27

We know that, Volume of a cylinder = πr2h We have, Ratio of radii = 2 : 3 Ratio of height = 5 : 3 Ratio volume of two cylinder = 22 × 5 : 32 × 3 = 20 : 27
