A circle with radius 2 units passes through the center A of another circle and intersects it at points B and C. Points A, B, and C divide the circumference of the smaller circle into 3 equal parts. One-tenth of the area of the smaller circle is outside of the bigger circle. What part of the area of the bigger circle is covered by the smaller circle?

Area = 12pi - 3.6pi = 8.4pi
