a circle with radius 2 , has a square inscribed in it. At the edges of square,circles are drawn taking sides as a diameter. Find the area of outer circles

• Area of circle with respect to diameter...... a*a=1/2*(d*d).
  
  =>a=2sqrt(2)...........(bcz d=2*2=4)
  =>area of square = 2sqrt(2)*2sqrt(2) =8
  
  =>area of circle = pi*r*r = 4pi,
  
  =>( Area of circle ) - ( Area of square ) = 4pi-8
  
  =>Therefore 4th part =(4pi - 8)/4
  
  =>Area of small semicircle =(pi*2)/2 = pi
  
  Therefore area of resin outside of circle = pi -(pi-2) = 2
  
  There for required answer will be = 4 * 2 = 8...this is our answer.

• diagonal of sq= diameter of circle
  root(2)* a=2*4
  a=2root(2)
  
  radius of new circle = 2root(2)/2=root(2)
  ans=pi*2=6.28

• Area of outer circles=4(Area of semicircle on diameter of square-(Area of big circle-area of square)/4)=8
