A quick super accurate way to divide the circumference of a circle.
Just find the number of points you want to divide the circle into in the list below and multiple the radius by the value (e.g. 5 slices of a 4" diameter circle would be 2 * 1.1756) then set your calipers/compass
The multipliers above were calculated with the following formula
DEG = 360/n where "n" is how many points around the circle you want
sin(DEG/2)*2 = your multiplier
