The length of a solid cylindrical cord of elastic material is 32 inches. A circular cross section of the cord has radius 1/2 inch. The cord is stretched lengthwise at a constant rate of 18 inches per minute. Assuming that the cord maintains a cylindrical shape and a constant volume, at what rate is the radius of the cord changing one minute after the stretching begins? Indicate units of measure.
