7. What is the arc length shown in the picture? Leave your answer in terms of pi.

Answer:
[tex]14\pi[/tex]
Step-by-step explanation:
Arc length = [tex]2\pi r(\frac{x}{360} )[/tex] where x is the angle
∴ For this question, the arc length is:
Arc length [tex]= 2\pi (8)(\frac{315}{360})[/tex]
Arc length = [tex]14\pi[/tex]
