Consider a regular heptagon whose sides all have lenght equal to 1. find the radius of the circle circumscribed about the heptagon.
Answers: 1
with known value (c = 1), and sides a and b have the same size of the radius of the circle we are about to find (a = b = r). 
[1]
, i.e., the total of degrees of the circle divided by 7, Â a = b (for the reason already explained), then, we have all elements to solve the equation [1] for the radius of the circle (a = b = r):
![\\ c^2 = 2a^2 [ 1 - cos(\gamma) ]](/tpl/images/0447/5188/14e3d.png)
![\\ 1^2 = 2a^2 [ 1 - cos(\gamma) ]](/tpl/images/0447/5188/eaa72.png)
![\\ 1 = 2a^2 [ 1 - cos(\gamma) ]](/tpl/images/0447/5188/671a9.png)
![\\ \frac{1}{2[1 - cos(\gamma)]} = a^2](/tpl/images/0447/5188/3a8ee.png)
![\\ a = \sqrt\frac{1}{2[1 - cos(\gamma)]}](/tpl/images/0447/5188/be917.png)
![\\ a = \sqrt\frac{1}{2[1 - cos(51\frac{3}{7})]}](/tpl/images/0447/5188/29900.png)
