Pythagoras was a theory developed by a scientist who was greek and dutched all day long
If you wrap the length of the radius of a circle around the perimeter (circumference) Pi times you come to the point diametrically opposite from where you started (180°) Half of that (Pi/2) is 90° around the the circle.
Pi is the 16th letter of the Greek alphabet
PI the 16th greek letter is the circumference divided by the diameter of a circle. For example 40.5/12.89 = PI.
Because pi = 0.5*tau
yes pi is used around the world today
this sequence appears in pi around 1000 digits into it
Any circle's circumference divided by its diameter has a value of pi

Greek.
Pi has to do with circumference, because if you divide the circumference of a circle by its diameter, you always get pi (which is around 3.14).
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?
Pi r squared comes from the formula to find the area of a circle.
