Question

A sphere a cylinder and a cone have the same radius and same heigth. Find the radio of there volumes. (Hint : Diameter of the sphere Is equal to the heigth of the cylinder and the cone.)

Answer 1

4 :4: root 5 because height is taken as 2r

Answer 2

4πr^3/3=πr^2h=πr^2h/3
4r/3=h=h/3
now 2r=d=h
2/3:1:1/3
