radius of curvature. n. (Mathematics) the absolute value of the reciprocal of the curvature of a curve at a given point; the radius of a circle the curvature of which is equal to that of the given curve at that point. See also centre of curvature.
Radius The radius is the distance from the center to any point on the edge. As you can see from the figure above, the diameter is two radius lines back to back, so the diameter is always two times the radius. See radius of a circle. Circumference The circumference is the distance around the edge of the circle.
