~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Draw the diagonal AC. It cuts the shaded area in two congruent parts of equal areas.
Each part is a quarter of the circle of the radius 4 cm minus the area of the isosceles
right angle triangle with the leg size of 4 cm.
So, the shaded area is
= = 8*3.14159265-16 = 9.132741cm^2. ANSWER
