The house we recently moved into came with a pair of old Kenmore "Heavy Duty" washer and dryer. The model number on the dryer is 87340100. I couldn't find the model on the net anywhere, so I am trying to figure out the capacity of the dryer in cubic feet. The radius of the inside is 13.75 inches, and the length of the inside is 20 inches. So using ¶r2h, I can up with roughly 6.65 cubic feet? Is that correct?
