66 cubic centimetres of silver is drawn into a wire 1 mm in diameter. The length of the wire in metres will be:

**Answer: Option A**

Let the length of the wire be h.

Radius = \(\frac{1}{2}mm=\frac{1}{20}cm. Then,\)

\(\frac{22}{7}\times\frac{1}{20}\times\frac{1}{20}\times h= 66 \)

h = \(\left(\frac{66\times20\times20\times7}{22}\right)=8400cm=84 m.\)
