Cone Surface Area and Volume Formulas


Todd Helmenstine

A cone is a pyramid with a circular base of radius ( r ) and the side length ( s ) is the length of the side.

s = √( r2 + h2 )

The surface area is the sum of the area of the base and area of the side.
Area of base: πr2
Area of side: πrs

Surface Area = πr2 + πrs
Volume = 1/3( πr2h )
