### Perimeter of Hendecagon given inradius Formula

P = 22*ri*tan(pi/11)

## What is hendecagon?

A hendecagon is an 11-sided polygon, also variously known as an undecagon or unidecagon. The term "hendecagon" is preferable to the other two since it uses the Greek prefix and suffix instead of mixing a Roman prefix and Greek suffix. A hendecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular hendecagon.
