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
