66 cubic centimeters of silver is drawn into a wire 1 mm in diameter. The length of the wire in metres will be:	Choose the correct answer:
A) 44 m  B) 84 m.  C) 89 m  D) 83 m  E) 42 m
Let the length of the wire be h.   Radius =1/2 mm=	1/20	cm.	Then,   = 22/7 x	1/20	x 1/20 x h = 66.   h =	66 x 20 x 20 x 7/22	= 8400 cm = 84 m.   Answer: 84 m.
