  	 * 1. left the circle with center at A is C, center is O(0, 0)
  	 * 2. find y = h for which x = a / 2 using the equation of the circle
  	 * 3. let (a / 2, h) be Q and (a, h) be S, find the angle QBS
  	 * 4. find the area of the segment QC (call it Z)
  	 * 5. the checkered area = a * (a - h) - 2 * Z
