The curvature of a circle is inversely proportional to its radius. What is the exact circumference of a circle with one-third the curvature of a circle of radius 1?

If a circle has a radius of 1, its curvature is inversely proportional to this = 1

 

A circle with a curvature of 1/3 of this must have a radius of 3

 

So....the circumference of this circle  =  2 pi * radius =  2 pi * 3 =  6pi ≈ 18.85 units
