I need to draw an arc for a piece of trim. The end points of the arc are 5 feet apart and the depth of the arc at the center point is 2 inches. What is the radius of the circle?
There ought to be an equation for this that would be far superior to trial and error, oui?

Pythagorean Theorem: 30^2 + (r-2)^2 = r^2.

disclosed,I believe.
Didn't even need trig. (which surprised me).
