The resistance of any conductor is directly proportional to the length of conductor and is inversely to its area of cross section. ... It depends on its cross-sectional area.

Yes, the resistance of a wire depends on its radius. Since resistance is inversely proportional to the area of cross section of the wire, and the cross section in turn is dependent on the radius(πr^2) ,therefore they dependon each other. ... Therefore R is inversely proportional to the square of the radius of the wire.
