ABCD is a square with area =625 in square. The circumfrence centered in circle is circunscribed by ABCD. Find the approximately value of the shaded area. Use pie = 3.14
I don't see any shaded area. The side length of the square is 25. The radius of the inscribed circle is 12.5. The difference in areas is
625 - pi(12.5)^2 = 134.1 in^2
= (1 - pi/4)*625
