The way in which you need to solve this is by using the formula: <span>R = ρL/A </span>That one is the formula that demonstrates <span>Resistance of a wire in Ω. The formula can be explained like this: </span><span>ρ is resistivity of the material in Ω-m </span> <span>L is length in meters </span> <span>A is cross-sectional area in m² </span> <span>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</span>
