ELI5: How do they calculate irrational numbers, like Pi, out to incredible digits, like over 1000 digits?

How does one create algorithms for irrational, transcendental numbers like pi?

Has any research investigated using different number systems to yield cleaner values for commonly used constants (Planck's constant, e, golden ratio, pi etc.)

If Pi is infinite, then does that mean if I draw a circle on paper, that circle has an infinite area?
-
Because a circle's circumference is pi times the diameter, the circumference is also the perimeter, and regular polygons perimeters are side length times the amount of sides, a circle has 3.14 sides, making it have more…
-
Since pi is the ratio between the diameter and circumference, it only accounts for the area of half a circle, therefore a pie consists of 2 pi, not one

I made a π formula using elliptic integrals
-
How are the digits of constants (eg pi) calculated to so many places?
-
How do we have such precision for pi?
-
ELI5: If circles and spheres are actual physical things in the universe, and Pi helps define circles and spheres, doesn't the fact that Pi is an infinite non-repeating decimal say something important about the physical…
-
Pi is the circumference of a circle, pi is infinite, the world is circular, therefore the world is infinite.

Why did π end up getting defined as the ratio of the diameter of a circle to it's circumference and not its radius? Isn't it needlessly complicating to have to use 2π all the time rather than just one?
