The surface area of a cone is given by the formula Where r is the radius of the circular base and s is the slant height of the cone. Area Perimeter and Diagonal of a Rectangle - Geometry Calculator. Surface AreaAdd the area of the base to the sum of the areas of all of the triangular faces.
If the truncation plane is parallel to the cones base it is called a frustumAn elliptical cone is a cone with an elliptical base.
The surface area of a cone is given by the formula Where r is the radius of the circular base and s is the slant height of the cone. It is equal to the sum of the curved surface and the base of the cone. The formula for the area of a cone is 314 times the radius times the side prl. In order to calculate its surface area or volume you must know the radius of the base and the length of the side.
