A circle of radius, r, has area pi r2.
The largest square inside it is made up of four isosceles triangles
whose equal sides are of length, r, and thus has area 1/2 r2.
Thus the area of the contained square is 2 r2.

You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
take off the circle at the bottom, and mold it into a square.
the circumfrence of a circle is pi times it's radius squared.
Area in square units = pi*radius2
