The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. So if you have a Diameter of 8 it would be 3.14 x 8 = 25.12. Now if you want this board to be turned round with the diameter of 8 it will need to be slightly larger because you are knocking off the corners. It looks like you had the right formula, you just didn't figure knocking off the corners. I usually use turbo cad for this , and that is on a different computer, if you need additional help I can work on it this evening.
