Q33 of 180 Page 4

Area of unshaded region = 2(Area of square – Area of quadrant)


Also,


Area of shaded region = Area of square – Area of unshaded region


= Area of square – 2(Area of square – Area of quadrant)


= 2(Area of quadrant) – Area of square


Area of quadrant


Area of square = (side)2


We have, radius of quadrant = side of square = 8 cm


Putting values, we get


Area of shaded region


= 32π – 64


= 32(3.14) – 64


= 36.48 cm2
