The term pi is a well known thing in all math classes. The number isn’t as simple as it sounds. It’s such a long number most teachers suggest you simplify it to 3.14. From reading this article I learned that pi also is used for useful things such as the common gps. It also helps save lives in the medical field with mri and cat scanners. Before reading this article I thought pi was simply just 3.14 with no real purpose, but after reading this I know that the term is way more than just an ordinary number.
