Q:
# What is the value of pi?

**The approximate value of pi, which is the ratio of a circle’s circumference to its diameter, is 3.14159265, according to Collins World English Dictionary.** It is impossible to represent its exact value fully and accurately since it is an irrational number with an unending, non-repeating decimal.

It is convenient at times to use a fractional approximation for pi. Though 22/7 can be used, it is only good to two decimal places. The fraction 355/113 is a significantly more accurate alternative. A mnemonic device for recalling pi’s value is to memorize the sentence, “May I have a large container of butter today?” The number of letters in each word can be counted to obtain 3.14159265.
