66 cubic centimetres of silver is drawn into a wire 1 mm in diameter. The length if the wire in meters will be: Pick one:
A) 76 m  B) 80 m  C) 84 m  D) 88 m  E) None of these
Explanation:   Let the length of the wire be h   Radius=1/2mm=120cm   πr2h=66   22/7∗1/20∗1/20∗h=66   =&gt;h=66∗20∗20∗7/22=8400cm=84m   Option 84 m
