6. Three unit circles are inscribed in a circle. Find the area of the largest circle touching these three circles?

• Firstly take the centre of first circle at co-ordinate(0,0),then you get (2,0) and (1,sqrt(3)) two other coordinate.now incentre will be calculated and it will be at point (1,1/sqrt(3)),so the radius of big circle will be "distance b/w incentre to any point i.e.1.154700+1"so final radius of big circle will be 2.1547.so area will be 14.585 sq. unit

• diameter of the bigger circle will b 4 as each circle has radius 1 so diameter of the smallr circles will be 2 so
  area will b 3.14*2*2=12.56

• radius of the biggest circle will be the sum of diameter of a circle and radius of third circle.
  R=2+1=3
  area= 22/7*(3*3)
  =28.27

• the radius of bigger circle is 2 times of smaller circle
  so the radius is 2
  area= (22/7)*(2*2)
  = 11.1
