Figure 11.1: Diagram for Problem 11.3.3 Figure 11.2: Diagram for Problem 11.3.4 11.3.4 In the diagram at right above, quarter-circles have been drawn centered at vertices A and C of square ABCD. Given that AB = 6, find the shaded area. 11.3.5? In the diagram at left below, XOY is a quarter-circle. Semicircles are drawn with diameters OX and OY as shown. Find the area of the shaded region given that XO = 4. Hints: 405, 458 Figure 11.3: Diagram for Problem 11.3.5 Figure 11.4: Diagram for Problem 11.3.6 11.3.6? In the diagram at right above, ABCD is a square of side length 4. Two quarter-circles and a diagonal are drawn as shown. Find the area of the shaded region. Hints: 121, 485, 450 Extra! 22/7 is a common approximation of ?. 355/113 is an even better approximation. In 1914, the great Indian mathematician Ramanujan provided the uncanny approximation
