Answer:

C. 4pi

Step-by-step explanation:

To find the length of arc XPY, we see that it is the same as arc XY! Since the length of the arc is 1/4 of the circumference of the circle, we first need to find the circumference. Since the circumference of a circle is 2pi*r, we can plug in the radius and get 16pi. Since 1/4 of 16pi is 4 pi, that is our answer.
