Hi,

the answer to the attached question is C). Although we don't need to get exact number, I am curious how to get circumference of the circle??

Thank you!

Well, the arc length that they give us is for major arc XYZ, if I'm reading the problem correctly. Since the angle for minor arc XZ would be 120, then the remaining angle for major arc XYZ would be 240. So 240/360 = 18/Circumference, so the circumference would be 27.
