Question

curved surface area of a cone or total surface area of a cone with diagram ​

Answer 1

The surface area of a cone is equal to the curved surface area plus the area of the base: \pi r^2 + \pi L r,πr

2

+πLr, where rr denotes the radius of the base of the cone, and LL denotes the slant height of the cone. The curved surface area is also called the lateral area.

Answer 2

Curved surface area of cone is πrl

(where 'r' is radius and 'l' is the slant height )

Total surface area of cone is πr(l+r)
