Lateral area sum volume formula of cylinder;

Lateral area of cylinder = perimeter of bottom circle × height?

Surface area of cylinder = upper and lower bottom area+side area?

Volume of cylinder = bottom area × height?

The volume of the cone = bottom area × height ÷3?

The side area of the cone = (pi× bus length× center angle) ÷ 180?

Surface area of cone = side area+base circle area.
