RESISTIVITY OF A WIRE

[From: ] [author: ] [Date: 12-02-14] [Hit: ]
ρ=AR/L = πe-6*2/37.9 = 1.......
A wire has a diameter of 2 mm and a length of 37.9 m, and is found to have a resistance of 2 . What is the resistivity of the wire?

I need to be able to explain this to someone ASAP, so please use formulas. Thank you!

Diameter =2mm, radius 1 mm
Area = π (mm)^2 = πe-6 m^2
ρ=AR/L = πe-6*2/37.9 = 1.66 e-7 Ωm
