A copper refinery produces a copper ingot weighing 121 lb. If the copper is drawn into wire whose diameter is 8.20 mm, how many feet of copper can be obtained from the ingot? The density of copper is 8.94 g/cm3. (Assume that the wire is a cylinder whose volume V = πr2h, where r is its radius and h is its height or length and see the table of physical data.)
Coverted to ________ ft
