Description : How does one find calculate pi?
Last Answer : answer:Here’s one way that’s inefficient, but pretty simple: 1 – ⅓ + 1/5 – 1/7 + 1/9…. Continue that pattern into infinity and it will approach pi/4. 22/7 is a rational number that is kind of close to pi, but it is not equal to pi, which is an irrational number so cannot be expressed as a fraction.
