Theorem: Pi

Math words: Definition in math terms: Pi, or p, is a mathematical constant, equal to about 3.14 (but with a gajillion digits after). It’s a fixed ratio of the circumference and diameter of any circle. Pi is an irrational number, which means it can’t be expressed as a fraction of two whole numbers.


My Words: Pi is the ratio of a circular object. The equation is the circumference divided by the diameter. You can measure a lid of a container first you measure the circumference of the circle. Next you measure the diameter. Then you divide the circumference by the diameter.

Pi used in the world today

Pi is used in engineering, and architecture. In engineering pi is used to construct the components, and control the moving parts in a machine. Pi is a very important part of architecture in help building the things we have today. It also helps with the construction of buildings, and bridges.
