The relationship between resistivity and circumference is inverse.

The resistance of a substance decreases as the surface area of that substance increases. The greater circumference presents a greater conduction surface.

Answer

The original answer describes resistance, NOT resistivity. Additionally, it is incorrect because resistance is inversely-proportional to cross-sectional area NOT circumference!

There is NO relationship between resistivity and the circumference of a material. Resisitivity is a constant at any given temperature and is completely unaffected by the dimensions of a material.
