Question 1203456
.
88 cubic centimeters of silver is drawn into a wire 1 mm in diameter. 
The length of the wire in meters will be.
~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let the length of the wire be L meters.


Use the formula for the volume of a cylinder

    V = {{{pi*r^2*L}}}.     (1)


In your problem,  V = 88 cm^3 = 88000 mm^3;  r = 1 mm;  L = 1000*L mm.

So, based on formula (1)

    88000 = {{{pi*1^2*1000*L}}},

which gives

    L = {{{88000/(3.14159*1000)}}} = 28.01 meters.


<U>ANSWER</U>.  The length of the wire is about 28 meters.

Solved.
