Now, I don't know of a single word for the very precise concept of a " three-dimensional finite right circular cone ", but you could probably remove the word " finite " from that description, since the concept of a " right circular cone " really makes sense only in the finite case . talk ) 17 : 52, 31 August 2011 ( UTC)

The lateral surface area of a right circular cone is LSA = \ pi r l where r is the radius of the circle at the bottom of the cone and l is the lateral height ( the length of a line segment from the apex of the cone along its side to its base ) of the cone ( given by the Pythagorean theorem l = \ sqrt { r ^ 2 + h ^ 2 } where h is the height of the cone ).
