Derivation of T.S.A. of cone and cylinder.

Question

Accepted Answer

Derivation of T.S.A. of cone and cylinder.

For a cylinder, the total surface area is the sum of the areas of the top and bottom circles and the lateral surface area.
For a cone, the total surface area is the sum of the area of the base circle and the lateral surface area.
The lateral surface area of a cylinder is given by 2πrh, where r is the radius and h is the height.
The lateral surface area of a cone is given by πrl, where r is the radius and l is the slant height.
The base area of a cylinder is πr^2 and the base area of a cone is πr^2.
The total surface area of a cylinder is given by 2πr(r+h) and the total surface area of a cone is given by πr(r+l).
