Well I did not really know a whole lot about pi until I did some research about it just now. Pi really confuses me and makes my mind spin to think about because of the fact that it goes on forever, and literally has no end. Because of the fact that Pi is irrational, it is impossible to express Pi as a ratio of two integers such as 22/7 or any other common fractions. Pi is used to find the area and circumference of circles, but because Pi is irrational, it is impossible to square a circle. This is really all I know about the number Pi.
