Is there a simple way to lay out different camber arcs?

The MASH-UP model design for the EAA weekend used a wing and horizontal stabilizer with a 6% camber, a smooth arc of constant radius. The downloadable plan had them full size, which was helpful.
 

 I spent a long time working through the math to locate the center, to draw my own of the proper chord and camber. (It's been more than half a century since I had geometry and trigonometry courses!) This simple sounding specification isn't that easy to achieve! Is there a simple formula for determining the distance from the chord line to the arc's center, to draw any chord wing with a wide range of curvature, from flat to say 10%?
