In the coordinate plane, a circle is defined with the center at point O(2, 3) and a radius of 5 units. Another circle is defined with the center at point P(2, -1) and also has a radius of 5 units. Determine the area of the overlapping region between these two circles.
Recall that the area of a circle is given by the formula: $$A = rac{22}{7} r^2$$ where $$r$$ is the radius of the circle.
