The resistance, r, of a wire varies directly as its length and inversely as the square of its diameter. if the resistance of a wire 2700ft long with a diameter of 0.26 inches is 9850 ohms, what is the resistance of 2800ft of the same type of wire with a diameter of 0.1 inches? (leave k in fraction form or round to at least 3 decimal places. round off your final answer to the nearest hundredth.)
