This will allow you to make proportioned shapes within the circle. For example -stars, triangles, octagons, etc. To find the divisions, multiply the diameter of the circle by the following multipliers.
For example:
6. Board Feet: A board foot is essentially a measure of wood, figured on the called size, not the actual finished size. Therefore a 2" x 4" x 8" contains 5.33 bd. ft. The theory is that you pay for what the mill started with before the wood is dried and planed. Thickness" x Width" x Length in feet, divided by 12 = board feet. T" x W" x L" ÷ 12 = Board ft. Thickness" x Width" x Length in inches divided by 144 = bd. ft. (T" x W" x L") ÷ 144 = Board ft.
