Editing Cone (section)

====Slant height====
The [[Slant height|slant height]] of a right circular cone is the distance from any point on the [[circle]] of its base to the apex via a line segment along the surface of the cone. It is given by <math>\sqrt{r^2+h^2}</math>, where <math>r</math> is the [[radius]] of the base and <math>h</math> is the height. This can be proved by the [[Pythagorean theorem]].
