If radius of a cylinder and a cone is double than cylinder. find the relation.

realtion between?
relation between cylinder and cone
between wat?? surface area? volume?


Cylinder = r
cone = 2r
volume of cylinder = πr²h
volume of cone = 1/3*π*(2r)²h = 4/3*πr²h

volume of cone = (4/3)*volume of cylinder

Assuming both have the sam e height.
Let radius of cylinder be x
volume: 3.14*x*x*h

and radius of cone=2x
so volume = 0.33*3.14*2x*2x*h

ratio= \frac{ 3.14*x*x*h}{0.33*3.14*2x*2x*h} =3:4
