### What is Meant by the Surface Area of a Cone?

In mathematics, the cone is a three-dimensional solid figure with the circular base. It tapers smoothly from the circular base to the point called the apex. The body of the cone has a curved surface.  If “r” is the radius and “l” is the slant height of the cone, then the formula to calculate the surface area of a cone is given by:

The curved surface area of a Cone =  πrl square units

The total surface area of a Cone = πr(l + r) square units
