Significance of Pi:
Pi, in case you don’t remember, is abbreviated to 3.14 but continues indefinitely. To date, it has been calculated by computer to over 1.2 trillion digits. Competitions exist for reciting the most digits by memory. As the world’s most famous mathematical constant, Pi is important to many formulas used in mathematics, science, engineering and statistics.
