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.
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
