Pi ( 3.142 approx.) is the amount of times the diameter of a circle can be measured along the circumference of a circle.

We know that Pi multiplied by the diameter of the circle is equal to it circumference. So we write C=PiD This means, as it says above, that a certain number of "Pi's" will be equal to the circumference.
