Question 1207916
•	The equation of the circle is x^2+y^2=36


This equation represents a circle with a radius sqrt(36) = 6 units

Area of circle = pi * r^2 = 36 pi unit ^2

The square is inscribed in a circle

The diagonal of the square is equal to the diameter of the circle.

The diameter of the circle is: Diameter=2r = 12

Let side of square = x
By Pythagoras theorem x^2+x^2= 144

2x^2= 144
x^2=72

x = 6sqrt(2)

Area of shaded portion = area of circle - area of square

=36 pi - 72  unit^2
