Who corrected the value of pi?
Around 250 BC, the Greek mathematician Archimedes created an algorithm to approximate π with arbitrary accuracy. In the 5th century AD, Chinese mathematics approximated π to seven digits, while Indian mathematics made a five-digit approximation, both using geometrical techniques.
What if there was no pi?
We’re not talking squares everywhere — a pi-less planet could mean no cell phones, no radios, no air travel or off-track betting. Even without pi, we’d still have circles — we just wouldn’t have any coherent means of expressing them, and calculating circular stuff would be an imperfect science.

What is the value of Pi?
Credit: Jeffrey Coolidge Getty Images Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
What is the value of Pi at 18 decimal places?
But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666…). (To only 18 decimal places, pi is 3.141592653589793238.) Hence, it is useful to have shorthand for this ratio of circumference to diameter.
What is the ratio of Pi to the size of a circle?
Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666…).
What is the use of Pi in physics?
Pi is most commonly used in certain computations regarding circles. Pi not only relates circumference and diameter. Amazingly, it also connects the diameter or radius of a circle with the area of that circle by the formula: the area is equal to pi times the radius squared.
