66 cubic centimetres of silver is drawn into a wire 1 mm in diameter. The length if the wire in meters will be:	Choose the correct option.
A) 76 m B) 80 m C) 84 m D) 88 m E) 90 m
Explanation:   Let the length of the wire be h   Radius=1/2mm=1/20cm   πr2h=66   (22/7)*(1/20)*(1/20)*h=66   =&gt;h=(66∗20∗20∗7) / 22   =8400cm   =84m   ANSWER IS 84 m
