    The drum radius for your dryer is 27 / 2 = 13.5 inches. Since you want the volume in cubic feet I think it is best to change all the measurements to feet before you calculate the volume. The height is 18 inches which is 18 / 12 = 1.5 feet. The radius is 13.5 / 12 = 1.125 feet. Thus the volume is . volume = 1.125 2 1.5 = 6.0 cubic feet. Penny
