Answer 2

Answer:

Let ABCD be a square inscribed in a circle of radius 'r'. Now, the diameter of circle is the diagonal of square.

Therefore, BD=2r. In △BDC, using Pythagoras theorem

BC ²+CD²=BD²

⇒a²+a² =(2r)²

⇒2a²2=4r²

⇒a ² =2r²

∴Area of square=2r²

Area of circle=πr²

Required ration=πr²

:2r²=π:²
