In the picture, Lines L1 and L2 are parallel, Lines L3 and L4 are parallel, L1 and L3 intersect on the circle, and L2 passes through the center of the circle. The angle theta equals pi/3, and radius R = 6. Find the area of the region A, which lies outside the circle and is bounded within the three line segments. Round your answer to the nearest hundredth.
