Description: View more at MathAndScience.com. In this lesson, you will learn what the number Pi is and why is important in Math. We will then use the number Pi to find the circumference of a circle. It turns out that the ratio of the circumference to the diameter of any circle is always the same number, which is Pi - for any size circle! We can then use this do find the circumference, diameter, or radius of any circle we wish.
