The radii of two cylinders are in the ratio of 2 : 3 and their heights are in the ratio of 5 : 3. The ratio of their volumes is
Let the radius of first cylinder be 2x and second cylinder be 3x. the height of first cylinder be 5y and second cylinder be 3y.
Now volume of first cylinder be ![]()
And volume of first cylinder be ![]()
Thus ratio = ![]()
![]()
Thus the ratio is
which option b is.
