resistance decreases with the increase of radius as the area of cross section increases.

heya friend..
.
here is your answer..
.
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 depend on each other.
Resistance = (resistivity×length of wire)/ area of cross section.
Therefore R is inversely proportional to the square of the radius of the wire.
