If diameters are equal then radii will also be equal
Volume of cylinder = πr^2h
Volume of cone = 1/3 πr^2h
Volume of sphere = 4/3 πr^3
Volume of cone : Volume of cylinder
= 1/3 πr^2 h : πr^2h
= 1 : 3
Height of sphere = 2r
h/2 = r
So volume = 4/3π (h/2)^3
= 4/3 h^3/8
= h^3/6
Volume of cylinder = πr^2h
Volume of cone = 1/3 πr^2h
Volume of sphere = 4/3 πr^3
Volume of cone : Volume of cylinder
= 1/3 πr^2 h : πr^2h
= 1 : 3
Height of sphere = 2r
h/2 = r
So volume = 4/3π (h/2)^3
= 4/3 h^3/8
= h^3/6
