Use the fact that the resistance of a wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. ​ A 13-foot piece of copper wire produces a resistance of 0.2 ohm. Use the constant of proportionality k = 0.000833 to find the diameter of the wire. ​ (Round the answer to three decimal places.) ​
