Q32 of 805 Page 1

In figure 6, three circles each of radius 3.5 cm are drawn in such a way that each of them touches the other two. Find the area enclosed between these three circles (Shaded region). [use

π = 22/7]




Area of shaded region = Area of equilateral triangle


- 3 Area of sector of circle


Area of equilateral triangle = cm2


Angle θ = 60⁰ because it is an equilateral triangle


Area of sector of circle =


Area of shaded region = 21.19 – 3 × 6.41 = 1.94 cm2
