Cylinder volume: π r 2h (cylinder volume is equal to the bottom area multiplied by the height)

Surface area of cylinder: 2π r 2+2π rh = 2π r (r+h) (bottom area plus lateral area).

Cone volume: 1/3 π r 2h

Cone surface area: π r 2+ 1/2π 2RL = π r (r+L) (L is the length of the bus, equal to the square of r plus the square of h under the root sign).
