A cone is a pyramid with a circular base of radius ( r ) and the side length ( s ) is the length of the side.**s = √( r ^{2} + h^{2} )**

The surface area is the sum of the area of the base and area of the side.

Area of base: πr^{2}

Area of side: πrs

**Surface Area = πr ^{2} + πrs
Volume = 1/3( πr^{2}h )**
