Draw a bunch of concentric circles with a drafting compass each 1 mm (or every 1/16 inch or whatever) larger in radius than the next smallest. You've then got yourself a radius ruler! Place behind the bend and note the circle that lines up with the inside and outside profile. These are the inner and outer radii of curvature.

On paper: draw lines perpendicular to the bend at two different places and measure the distance to their intersection. (If the distances aren't equal, the bend is not circular.)
In a real item: about the same, but you can't "draw" lines. You might be able to use a straight object (ruler or yardstick).
