Is there a formula or chart for detemining the length of a piece of wood that's used as a segment in a circle?
Example: If I cut eight pieces of wood equal lengths and miter the ends at 22.5° and glue them together, I will end up with a semicircle. The question is, to make a semicircle that's 30 inches in diameter, what is the length that I need to cut each segment?
I would assume that there would be an existing chart or formula somewhere to figure this out...
