Answer:

arc = 7 pi

Step-by-step explanation:

The length of the arc is circumference

C = 2 * pi *r

C = 2 * pi *4

C = 8 pi

A circle is 360 degrees. The arc is 315 degrees

The arc is 315/360 of the circle, that is 7/8 of the circle, so it will be 7/8 of the circumference

7/8C = 7/8 (8pi)

arc = 7 pi
