Given that the diameter of the wire is;
[tex]D(mil)=80.81\text{ millimeters}[/tex]We can find the diameter in inches using the conversion below;
[tex]1\text{inch = 25.4mm}[/tex]We would divide the diameter in millimeters by 25.4 to get its value in inches.
Therefore, the diameter in inches would be;
[tex]\begin{gathered} D(\text{inches)}=\frac{80.81}{25.4} \\ D(\text{inches)}=3.18150 \end{gathered}[/tex]Answer: 3.18150 Inches
