To find the surface area of a cone, you need to calculate the area of the curved surface (lateral surface area) and the area of the base.
The curved surface area of a cone can be found using the formula: A = π * r * s, where A is the curved surface area, π is a mathematical constant which can be approximated to 3.14, r is the radius of the base, and s is the slant height.
The area of the base of a cone can be calculated using the formula: A = π * r^2, where A is the area of the base and r is the radius of the base.
To find the surface area of the cone, you need to calculate the curved surface area and add it to the area of the base.
