The way in which you need to solve this is by using the formula: R = ρL/A That one is the formula that demonstrates Resistance of a wire in Ω. The formula can be explained like this: ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m² A = πr², r is radius of wire in m As soon as you have your numbers, you can replace and proceed to get the asnwer
