Answer:
B. π
Step-by-step explanation:
If you're looking for the length of an arc, you can easily find it through the circumference. Because we know that the formula for circumference is 2πr, then we can find that it is 6π (in terms of π), using the length of XY as the radius. As given to us, the measure of angle XYZ is 60°. Since the total degrees in a circle are 360°, we can see that the arc is taking up a sixth of the entire circle. Now, because we are trying to find the length of the arc itself, using the ratio of the arc to the circle, we can do 6π÷6=π
