someone asked me to make them a pentagram out of wood.  So I thought up this
puzzle on my way home from the lumber yard.....

I have a circle...Lets say the diameter is one.
What are the lengths of the sides of the following inscribed regular
polygons?


triangle

square

pentagon

hexagon

7-gon....(my geometry teacher said that the other names are wrong  call it a
7-gon )

octagon

Also is there a simple formula f(x) that you put in the number of sides and
get the lengths of the sides?
