Answer: 2π inches or 6.28 inches.

Explanation:

To solve this problem you must apply the formula shown below:

$arclenght=(2r\pi)(C/360)$

Where r is the radius and C is the central angle.

Subsitute values. Therefore, you obtain that the length of the arc is:

$arclenght=(2(8in)\pi)((45/360)$

$arclenght=2\pi\ in=6.28in$
