Answer: 39.28 in.

Explanation:

Given

Diameter of patch
d=12.5\ in.\quad \quad [r=(12.5)/(2)]

Assume patch is in the shape of the circle

The circumference of the circle is given by
2\pi r

Circumference of the patch


\Rightarrow 2\pi * (12.5)/(2)\\\\\Rightarrow 2* (22)/(7)* (12.5)/(2)\\\\\Rightarrow 39.28\ in.
