    I think I'm wrong, because I'm not sure if I used the proper formula...?

    @TheHero given any figure volume is got by the product of base area and height .Remember!

    Just divide the volume of Y by the volume of X. Pi x 60 x 60 x 40 / Pi x 15 x 15 x 10. If the final answer is 1.06 then ur correct. Y : X = 1.06 : 1 Which, by law of proportions means Y = 1.06 X; try it out

    @AravindG somehow i think 1.06 is not right..radius itself is 4 times or something;
