Learn about the definition of pi in relation to a circle with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

For example, it is used to calculate the circumference of a circle (U = 2πr) or the area of a circle (A = πr ^ 2). What is mathematically interesting is that pi has no regularity or repetition.
