Areas related to Circles....URGENT...!!

Dear Student

Side of the square inside the circle=   D cos45

Area of teh square =  D²cos²45  =D²/2  ==>(1)

Area of the circle =  π (D/2)²=  π D²/ 4    ==>(2)

Area of teh shaded region you required  A= [  Eqn(2)-Eqn(1)  ] /2  =   [ π D²/ 4 - D²/2 ] /2  =(D²/ 8) ( π-2)

If D=2    A= ( π-2)/2  Sq units.

No need to consider the outer square side at all.
