• murshid_islam
In summary, Pi Day is a holiday celebrated on March 14th to honor the mathematical constant π. This date was chosen because the first three digits of pi are 3.14. Pi is important because it has numerous applications in mathematics, science, engineering, and technology. Pi Day is celebrated by organizing competitions, eating circular foods, and participating in math-related activities. The number 3.14 is significant because it is the approximate value of pi, which is the ratio of a circle's circumference to its diameter. Pi is an irrational number and can be approximated using various methods, with the current record for calculating the most digits being over 31 trillion.
