Alg2_8_2_Ex4 OR Alg2_8_2_Ex4The electrical resistance of a wire varies directly as its length
and inversely as the square of its diameter. One hundred meters of wire with a diamter of 6 mm has a
resistance of 12 ohms. Eighty meters of a second wire of the same material has a resistance of 15
ohms. Find the diameter of the second wire.
