1. One of the two points of an orbit, as of a planet or satellite, which are at the greatest and least distance from the central body, corresponding to the aphelion and perihelion of a planet, or to the apogee and perigee of the moon.
2. In a curve referred to polar coordinates, any point for which the radius vector is a maximum or minimum.
3. Same as Apse.
Astronomy, point at which heavenly body is most or least distant from center of attraction. higher apsis, most distant point. lower apsis, least distant point.

1. The property of something that is great in magnitude; SYN. mass, volume.
2. The property possessed by a large mass.
ETYM Latin circumferentia.
In geometry, the curved line that encloses a curved plane figure, for example a circle or an ellipse. Its length varies according to the nature of the curve, and may be ascertained by the appropriate formula. The circumference of a circle is pd or 2pr, where d is the diameter of the circle, r is its radius, and p is the constant pi, approximately equal to 3.1416.
1. The length of the closed curve of a circle.
2. The size of something as given by the distance around it; SYN. perimeter.
ETYM Icel. gjörth girdle, or gerth girth; akin to Goth. gaírda girdle. Related to Gird to girt, and cf. Girdle.
The distance around a person's body.
ETYM Italian scopo, Latin scopos a mark, aim, Greek skopos, a watcher, mark, aim; akin to skopein to view, and perh. to Eng. spy. Related to Skeptic, Bishop.
An area in which something acts or operates or has power or control; SYN. range, reach, orbit, compass, ambit.

3. A large magnitude
4. (Informal) The actual state of affairs; SYN. size of it.

ETYM French, from Latin volumen a roll of writing, a book, volume, from volvere, volutum, to roll. Related to Voluble.
In geometry, the space occupied by a three-dimensional solid object. A prism (such as a cube) or a cylinder has a volume equal to the area of the base multiplied by the height. For a pyramid or cone, the volume is equal to one-third of the area of the base multiplied by the perpendicular height. The volume of a sphere is equal to 4/3 x pr3, where r is the radius. Volumes of irregular solids may be calculated by the technique of integration.

2. A relative amount.
3. The amount of 3-dimensional space occupied by an object.
4. The magnitude of sound (usually in a specified direction); SYN. loudness, intensity.
