Get Polygon Side Length From Radius

  1. Sep 14, 2008 #1
    I'm doing some programing and I am wondering how I can find the length of a Polygon's side (variable number of sides) from the radius (distance between center and one corner).

    Thank you

    It is a simple application of geometry and Trig.

    You know the side length and included angle (this is determined by the number of sides). Draw a picture and apply the definition of the Sin.
