| I need some trig help. I need to create a bending form but I need
| the diameter (or radius, it doesn't matter) based on the following
| The diameter of a circle formed by an arc with a 1/8" apex over a 1
| 5/16" base length. Yeah, I know some of the terms are wrong, but
| I'm a long way removed from Mr. Cole's high school trig class.
Sorry to have arrived so late. This gets asked enough that I put up a
web page with diagram and step-by-step algebra at the link below.
