# Slant Height of a Cone Calculator

A cone is a 3D shape with only one vertex, having a circular base. The top most point of a cone is the vertex or apex. The slant height of a cone is defined as the distance from the apex to any point lying on the circumference of the base. The slant height is usually denoted by letter 'l' or even sometimes by the letter 's'. In the right circular cone calc, find l by just entering radius and height as inputs. The slant height of a cone calculator helps to find the height of a cone.

Code to add this calci to your website

#### Formula:

Slant Height = √((r^{2})+(h^{2}))
**Where,**
r = Radius
h = Height

#### Example

**A cone has a radius of 7 cm and height of 11cm. Find its Slant height?**

Slant Height = √(49+121)

= √170
