Perimeter is defined as the distance around a given area. Think of calculating how long a fence would be that completely surrounds your property. Perimeter is generally calculated by adding the lengths of all of the sides. Circles have no straight lines that are easily measured. Therefore, they require a special formula to determine perimeter.

Learn that the perimeter of a circle has its own special name, called "circumference." The symbol is a capital C. It is calculated using the formula $π \times d i a m e t e r$ , or $3.14 \times d = C$ . It can also be calculated by Pi x (2 x radius) = C or $3.14 \times (2 \times r)$ $= C$
