Question

formula of toatal surface area of cone​

Answer 1

Answer:

The surface area of a cone is equal to the curved surface area plus the areaof the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr, where r denotes the radius of the base of the cone, and L denotes the slant height of the cone. The curved surface area is also called the lateral area.
