The radius of a circle is 5 inches so, the angle measure of the arc is
$(\pi)/(5)$ radians or 36 degrees.

The formula to find the angle measure (in radians) of an arc in a circle is given by:

$\theta=(\ell)/(r)$

where:

θ is the angle measure in radians,

ℓ is the length of the arc,

r is the radius of the circle.

In this case, you have
$\ell=\pi \text { inches}$ and
$r=5 \text { inches}$ . Plugging in these values into the formula:

$\theta=(\pi)/(5)$

So, the angle measure of the arc is
$(\pi)/(5)$ radians.
