Surface area of cone = Area of sector + area of circle = πrs + πr 2 = πr(r + s) Surface area of a cone when given the slant height. Example: A cone has a circular base of radius 10 cm and a slant height of 30 cm. Calculate the surface area. Solution: Area = πr(r + s) = = 1,257.14 cm 2

3 sie 2023 · The surface area (total surface area) of a cone is the entire space occupied by the flat circular base of the cone and its curved surface. The surface area is expressed in square units such as m 2, cm 2, mm 2, and in 2. Here we will discuss how to find the surface area of a right circular cone.
To find the curved surface area of a cone, we multiply the radius and slant height of the cone by pi(π), and the formula which is used to find the lateral surface area of a cone is, CSA of cone (LSA of cone) = πrl, where 'r' is the radius of the base and 'l' is the slant height of the cone.
26 gru 2022 · To find the surface area of a cone if you know the length of the slant, use the formula (πrs)+πr^2. Put the value of the radius of the circle at the bottom of the cone into the formula where you see an “r” and be sure to square it where necessary.
