# formula for wetted perimeter of a circle

Circle. is a simple shape consisting of those points in a plane that are equidistant from a given point, the centre. The distance between any of the points and the centre is called the radius.Perimeter Formulas for Geometric Figures. A perimeter is a path that surrounds a two-dimensional shape. The term may be used either for the path or its length—it can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference.

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." Perimeter Formulas The perimeter of any polygon is the sum of the lengths of all the sides. Note: "ab" means "a" multiplied by "b". "a2" means "a squared", which is the same as "a" times "a".square 4a. rectangle 2a 2b. triangle a b c. circle 2pi r. Perimeter of the circle is the full distance around the edge of a circle. Perimeter of the circle can be measured in millimeters, centimeters, meters and kilometers.
