The shape of the drum in your dryer is a circular cylinder, and the volume of a cylinder is. volume = (area of the base) (height) Since the base of your cylinder is a circle the volume is. volume = radius 2 height. where is approximately 3.1416. 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 volumeGet Price
