2.2 cubic dm of lead is to be drawn into a cylindrical wire 0.50 cm diameter. Find the length of the wire in meters.  Choose the correct choice from the following options:
A) 110  B) 111  C) 113  D) 112  E) None of them
Let the length of the wire be h meters. Then,   ∏ (0.50/(2 x 100))^2 x h = 2.2/1000   =h = ( (2.2/1000) x (100 x 100)/(0.25 x 0.25) x (7/22) ) = 112 m.   Answer is 112.
