𝞹 - The area of the Square & Unit Circle ~0^0~

My Math II Professor told me that our nature operates seamlessly with polar coordinates and the geometry of spheres. but we as humans prefer a cartesian coordinates system. For one reason that our planets of the solar system are also kinda like the sphere,

➤ If you have a unit circle, the area of that circle would be 𝞹, 

The area A = 𝞹r^2, Since the r=1

➤ If you had asked to create a square with the exact same area, the length of that square would be L = √𝞹.
