Pi is 3.14 or 22/7. It is used to find diameter or circumference of a circle. It is actually the circumference of a circle. To solve for Pi or circumference of a circle you will need to find the size of the outer layer of the circle, then find half the measure of the circle. Now divide the outer layer measurement with the half measure and that will be your answer. Your answer may vary from the size of the circle, but still pi is the most accurate measurement of pi. 22/7 is another way of saying pi. It is the fraction form of pi and is not commonly used. We use 22/7 when solving fractions. 3.14 is a decimal, but it is much more simple to multiply it.22/7 is 22 divided by 7 and that is 3.14 with a line over three because it is just a very long number. There are so many digits we can't even count it all. The digits seem to never end and goes on forever.
Most people don't use pi because it is for finding the amount around a circle. People don't need to find circles, but squares. During Pi day in my algebra class, there will be an activity where you memorize as many Pi digits as you can. Did you know that pi is a homophone? It sounds like pie, but is actually very different from it. That is what homophone mean: sound the same, spell differently, and have different meaning.
