1) The central angle AOB measures 120 degrees and the radius of the circle is 4 meters. Find the length of the minor arc AB.
2) The central angle AOB measures 120 degrees and the radius of the circle is 4 meters. Find the area of the sector created by angle AOB and it's intercepted arc AB.

An arc length is just a fraction of the circumference of the entire circle. So we need to find the fraction of the circle made by the central angle we know, then find the circumference of the total circle made by the radius we know. Then we just multiply them together.
