The electrical resistance

of a wire varies directly with the length I of the wire and inversely with the square of the diameter

of the wire. If a wire 416 feet long and 4 millimeters in diameter has a resistance of 1.26 ohms, find the resistance in a wire that is 276 feet long with a diameter of 3 millimeters. The resistance in the wire is approximately ohms. (Round the final answer to two decimal places as needed. Round all intermediate values to six decimal places as needed.)
