The line that goes round or encompasses a circular figure; a periphery.

A circle; anything circular.

The external surface of a sphere, or of any orbicular body.

To include in a circular space; to bound.

the distance around a circle; 3.14 * D or pi times the diameter

The length around a circle.

(3) The distance around a circle or sphere.

The size of something as given by the distance around it.

the outer boundary of a circle or spherical object

The outer boundary of a circular area.

The boundary of a given area.

The line that goes round or encompasses a circular object.

sometimes used for the boundary of a circle but more usually the length of the boundary. If the radius of a circle is units, and the diameter units, then the circumference is 2Ï€r, or d units.

The length of the outer boundary of a circle. Example: Circumference=Pi*Diameter.

the length of the closed curve of a circle

a species of perimeter, which is generally defined as the sum of the lengths of all sides of a two-dimensional object

The outermost edge of the circle and is made from an infinite number of point that are of equal distance from the center of the circle. It is found by using the formula 2, where is approximately 3.1416 and is the radius. (See Pinhole Camera Observatory)

The length of the outside of a circle.

Length of a circle. The measurement around the perimeter.

the distance around a circle; equals 2 x x radius or x diameter (C = 2 r or

distance around the fullest part of the ball.

the perimeter of a circle is called its circumference.

the distance around (perimeter of) a circle.

This is the distance around a circle.

the distance around a circle, often denoted by the (uppercase letter) ; it is found by either of the quantities 2Ï€r (where is the length of the radius) or Ï€d (where is the length of the diameter)

The distance around a circle; the formula for circumference of a circle is pi times the diameter (C = TT

The perimeter of a circle; the external boundary or surface of a figure or object.

The circumference is the distance around an object. The circumference of a circle of radius r is 2Ï€r .

The distance around the outside of a circle.

The distance around a circle; equals 2 Ã— Ï€ Ã— the radius or Ï€ Ã— the diameter (C = 2Ï€r or Ï€d).

the (measure of the) perimeter of a circle.

The line bounding a circle, a rounded surface or an area suggesting a circle. The outer perimeter of a circle.

The distance around a circle also known as the perimeter. It is calculated by multiplying the diameter of the circle by PI (3.14...). (i.e., C = " pi"d).

The circumference is the distance around a closed curve. Circumference is a kind of perimeter.
