    What is the area of the largest square that you can draw in a cricle which has a radius of 4 meters?

    Yep, easy as a pie. A side of the square equals radius time square root of 2 (4 * sqrt(2)) and (4*sqrt(2))² = 16 * 2 = 32.

    Actually I do not understand how you get it. I am sure you did the same as below.

    The solution is:

    1) Draw a square in a circle which has radius of 4.

    2) Divide it into two triangles from the corners of the square, both triangles will be sharing the same hypotenuse.

    3) The hypotenuse is 8 meters since the diameter of the circle is 8. Note that the other sides of the triangles are same since the square has 4 same sides.

    5) So; we need to solve it from the pythagoras formula: a²=b²+c². We know ''a'' is 8 and we know ''b'' and ''c '' are the same. So, let b and c be X as one side of the square or the same sides of the triangles.

    8²= 2x²

    2x²= 64

    x² = 32

    x = Square Root 32m

    5) Finally, we know one side of the square. The answer is:

    A= (Square Root 32m)x(Square Root 32m)

    A= 32m²

    Eeze! Meeze! Cheeze!

    Yep, I did the same. (without mentioning the pythagorean) In a square it's side line is equal with the half diagonal times squareroot of 2. If it's a cube, then the side line is equal with the half diagonal times squareroot of 3.
