R column = 2 5r cone.

H-column = 5 2h cone.

S column = *(2 5r cone) 2 * (5 2h cone) = 2 5 r cone 2h cone s s cone = 1 3 * r cone 2*h cone.

S-cone: S-column = 5 6

Solution: Let the circumference of the bottom surface of the cylinder be c, and the height should be h

Derive: cylinder area = c h

The circumference of the bottom surface of the cone is five-twoths c (

The height is two-fifths h(

Get: cone area = 1 3

The volume of the conic is one-third of the volume of the cylinder.
