Answer:
$14.93
Step-by-step explanation:
If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.
Total cost=circumference* cost per inch
Circumference of a circle is given by
[tex]C=2\pi r[/tex]
Where r is radius. Substituting 4.75 inch for r then
[tex]C=2\pi\times 4.75=29.857142857142\\C\approx 29.86 inch[/tex]
Cost=29.86*0.50=$14.93
