    Wire length from resistance and diameter using direct and inverse variation

    Okay thank you! I wasn't sure where to post it. I got .0212 for K. I hope I did that right.

    Wire length from resistance and diameter using direct and inverse variation

    The electrical resistance of a wire varies directly with the length of the wire and inversely with the square of the diameter of the wire. If a wire 50 feet long and 2 millimeters in diameter has a resistance of 0.265 ohms, find the length of a wire of the same material whose resistance is 0.068...
