It doesn't matter how big or tiny a circle is, pi always equals the same number.
When starting off in math, students are introduced to pi as a value of 3.14 or 3.14159. Although pi is an irrational number, some people estimate it using rational expressions, like $\frac{22}{7}\text{of}\frac{333}{106}$ .
