Relationship between cylinder and cone

The conic product with equal base and equal height is one third of the volume of a cylinder.

For cones and cylinders with equal volume and height, the bottom area of the cone is three times that of the cylinder.

For cones and cylinders with equal volume and base area, the height of the cone is three times that of the cylinder.

The ratio of lateral area of a cylinder with equal bottom and equal height to a cone is: S cylinder side /S cone side =, where R is the radius of the bottom surface and H is the height.
