Any math whizzes out there? I'm trying to remember how to calculate the radius or diameter of a circle when I have a known arc (?) I'm trying to make a permanent template for the rockers on a rocker board

The length of the straight edge is 15" and the "height" at the center of the rocker is 3.5" It's been a long time since trig so any help is appreciated.
