1.	a squre of diagonal 8cm is inscribed in a circle . find the area of shaded part
Answer» Since it is a square, all 4 sides are equal.. the diagonal is also given..2AB^2=AC^2AC=4AB^2=8AB=2root2 cmSide of the square is equal to diametre of the circle..Therefore radius of the circle is root2 cm..Area of the circle= 22/7×2root2×2root2 = 22×8/7Area of square = 2root2×2root2=8cmTherefore area of shaded region = 8-(22×8/7) = 8-25/-18/ .. negative areas within bar brackets
