Perhaps, related to "What is arccos(sqrt(Pi)/2)?"
... which is the trigonometric function that defines the vertex angle of a Pythagorean triangle that squares the circle:
arccos(.88622692545275801364908374167057..)
= 27.597112635690604451732204752339.. degrees.
For a circle having a diameter equal to 2, the triangle's long side (circle's chord; side of its square)
= sqrt(Pi) and its hypotenuse = 2 (circle's diameter), with the vertex point on the circumference.

What is the area of a regular octagon with a side length of 5?
It is about 120.71 square units.A= 2(1 + sqrt2)S²For S = 5A = (2 + 2sqrt2) 25A = 50 + 50 (sqrt2)A = 50 + 70.71 = 120.71
How do you find perimeter of a square inscribes in a circle?
one side of the square inscribed in a circle of radius r is sqrt2 * r (the square root of two times the radius) So the perimeter is 4 * sqrt2 * r
