I can confirm with AutoCAD your findings on the different setups if you like
or can send you a PDF file with drawings using your sizes.

Each segment will be 11.125" wide.

I get 11.3 inches.

11.3 is 1/10th of the circumference of the circle, not the width of that
segment.

Thanks for the responses guys. The circles are all less than my example of
36",
the biggest is just over 35 3/4 on the inside.
Some are as small as 12"

I will try some of the formulas and see if I can figure out which one is
easy to
use.
I also need to calculate on 6, 8 and 12 segments.
