A copper rod of diameter 1 cm and length 8 cm is drawn into a wire of length 18 m of uniform thickness. Find the thickness of the wire.

Explanation

To solve the problem of finding the thickness of the wire drawn from a copper rod, we will follow these steps:

### Step 1: Calculate the Volume of the Copper Rod
The volume \( V \) of a cylinder is given by the formula:
\[ V = \pi r^2 h \]
where \( r \) is the radius and \( h \) is the height (length) of the cylinder.
