<PRE><B>Question 1081380</B>
You most likely want diameter of the wire in inches.  Volume of the initial copper piece will be equal to the volume of the resulting wire.


36 inches is 1 yard.


d, for the DIAMETER, in inches;
All length or distances are used in their inches units;

{{{4*2*(1/2)*inch*inch*inch=100*36*pi*(d/2)^2*inch^3}}}
d is for diameter, in inches.


If you can understand that equation then the steps for solving d should be clear, uncomplicated.


{{{4=3600*pi*(1/4)d^2}}}


{{{d^2*pi*(3600/4)=4}}}


{{{d^2=4(4/3600)(1/pi)}}}


{{{d=(4/60)(1/sqrt(pi))}}}


{{{d=(1/15)(1/sqrt(pi))}}}


{{{d=1/(15*sqrt(3.14159))}}}


{{{highlight(d=0.0376)}}}, inches</PRE>
