It has been awhile since I used that method to figure the size of the wood, if I remember correctly using that method the diameter will be like drawing a circle around each point, so the larger the width of the boards the more that will be cut down when turning. Instead of wasting the material you can cut one piece of scrap to the size you decide to use and then cut into the number of pieces you plan to use and placing them in a circle. You can get a 30 dollar program at Amazon, or office depot called Turbo cad you can draw it up on a computer screen and figure it out without making any saw dust or using any materials .

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.
