Dear visitor
Please, read the answer more attentively. It's stated there that diagonal of the small square(not initial one!)-the square inscribed in the circle equals to diameter.

but its not given that the circle's diameter is equal to the diagonal. its only given that its in line with it...

Draw a square incribed the circle. ( You have half that square already; 2
sides of that square are the segments created by the circle and the
large square)

Diameter of the circle is equal to diagonal of that small square.

Using small square's diagonal to calculate the its side.

Calculate the small square's area.

The circle's area = small square's area + 4 additonal pieces ( on the
original graph, you can see there are two of them already. After drawing
the small square, you will see all)

So area of 4 pieces = The circle's area - small square's area

If the circle were incribed in the big square, the remain area would be: Big square'area - circle's area

However, 2 small pieces is outside the big square, then the remain area will be:

(Big square's area - circle's area ) + 2 small pieces

And we have known how to calculate each item in the equation as I mentioned above.

Hope it helps.
