Question

what is that important thing that is related to circle and circumference

Answer 1

Our Circle

We begin with a circle. After all, the number pi is pronounced the same way as a slice of pie from a big round yummy apple pie. In math, the number pi is approximated by 3.14 but the number actually goes on forever. We have to have a circle because both the circumference and diameter are parts of a circle.

The circumference is the distance around the circle, and the diameter is the distance across the circle going through the center. Think of the circumference as the amount of whipped cream you need to go all the way around the pie, and think of the diameter as the cut you make to cut the pie in half exactly.

The Formula

In math, we have a formula that relates these two parts of a circle. This formula is called the circumference formula, and it is C = pi*d where C stands for the circumference and d stands for the diameter. And pi is pi or 3.14.
