shaded area = circle area - square area
hint ... a square is also rhombus. does your text have an area formula for a rhombus based on the length of its diagonals?
I am not sure how to figure this problem out and I have looked all through my math book and cannot find it!
Q: In the figure shown, square wxyz is inscribed in circle O. Also, OM ⊥ XY and OM=2. Find the area of the shaded region.
