Q8 of 27 Page 228

Four equal circles, each of radius ‘a’ touch one another. Find the area between them.

Radius of each circle, r = a


We need to find the shaded area,


If we connect the four centers we will get a square of side 2a.


Area of square,AS = (2a)2 = 4a2




Area of shaded region = AS – [4 × AQ]
