## Introduction: Quickly Divide a Circle Perfectly

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

- n/a
- n/a
- 1.7321
- 1.4142
- 1.1756
- 1.0000
- 0.8678
- 0.7654
- 0.6840
- 0.6180
- 0.5635
- 0.5176
- 0.4786
- 0.4450
- 0.4158
- 0.3902
- 0.3675
- 0.3473
- 0.3292
- 0.3129

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
