What is Hendecagon?

A Hendecagon is an 11-sided polygon, also variously known as an undecagon or undecagon. 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.

How to Calculate Inradius of Hendecagon?

Inradius of Hendecagon calculator uses Inradius of Hendecagon = Side of Hendecagon/(2*tan(pi/11)) to calculate the Inradius of Hendecagon, The Inradius of Hendecagon formula is defined as the straight line connecting the incenter of the Hendecagon and any point on the circle that touches all edges of the Hendecagon. Inradius of Hendecagon is denoted by r_i symbol.

How to calculate Inradius of Hendecagon using this online calculator? To use this online calculator for Inradius of Hendecagon, enter Side of Hendecagon (S) and hit the calculate button.
