Answer: 2π inches or 6.28 inches.
Step-by-step explanation:
To solve this problem you must apply the formula shown below:
[tex]arclenght=(2r\pi)(C/360)[/tex]
Where r is the radius and C is the central angle.
Subsitute values. Therefore, you obtain that the length of the arc is:
[tex]arclenght=(2(8in)\pi)((45/360)[/tex]
[tex]arclenght=2\pi\ in=6.28in[/tex]
