What is the resistance of 125 m of aluminum wire that has a diameter of 0.8118 mm?
The resistivity of aluminum is 2.824 x 10^-8 (omega) m.
I need help with the set up. we've been using R = V/I, but haven't had anything with resistivity. I don't know where to place this, diameter, etc. Please help. Thank you.

resistance= resisitivyOfAluminum*length/area
figure the area of the crosssection, and look up of resistivity of alumnium
