A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a geometrical object in three-dimensional space that is the surface of a ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk"). Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.

A half sphere; one half of a sphere or globe, when divided by a plane passing through its center.

To put in or within a sphere.

Half of the terrestrial globe, or a projection of the same in a map or picture.

(mathematics) A regular three-dimensional object in which every cross-section is a circle; the figure described by the revolution of a circle about its diameter . Category:en:Surfaces

The people who inhabit a hemisphere.

A spherical physical object; a globe or ball.

Half of the terrestrial globe

The apparent outer limit of space; the edge of the heavens, imagined as a hollow globe within which celestial bodies appear to be embedded.

Half of a sphere

Any of the concentric hollow transparent globes formerly believed to rotate around the Earth, and which carried the heavenly bodies; there were originally believed to be eight, and later nine and ten; friction between them was thought to cause a harmonious sound (the music of the spheres).

Either half of the cerebrum

(mythology) An area of activity for a planet; or by extension, an area of influence for a god, hero etc.

(figuratively) The region in which something or someone is active; one's province, domain.

(geometry) The set of all points in three-dimensional Euclidean space (or n-dimensional space, in topology) that are a fixed distance from a fixed point .

(logic) The extension of a general conception, or the totality of the individuals or species to which it may be applied.

(transitive) To place in a sphere, or among the spheres; to ensphere.

(transitive) To make round or spherical; to perfect.

A body or space contained under a single surface, which in every part is equally distant from a point within called its center.

Hence, any globe or globular body, especially a celestial one, as the sun, a planet, or the earth.

The apparent surface of the heavens, which is assumed to be spherical and everywhere equally distant, in which the heavenly bodies appear to have their places, and on which the various astronomical circles, as of right ascension and declination, the equator, ecliptic, etc., are conceived to be drawn; an ideal geometrical sphere, with the astronomical and geographical circles in their proper positions on it.

The extension of a general conception, or the totality of the individuals or species to which it may be applied.

A particular aspect of life or activity;

A solid figure bounded by a spherical surface (including the space it encloses)

A three-dimensional closed surface such that every point on the surface is equidistant from the center

The apparent surface of the imaginary sphere on which celestial bodies appear to be projected

Spheres are used to model perfectly round objects in various fields, such as planets in astronomy and balls in sports.

Yes, a sphere can be divided into multiple hemispheres, but typically "hemisphere" refers to one of two halves.

The surface area of a sphere is calculated using 4πr², while a hemisphere’s surface area includes both the curved surface and the area of the circular base.

Hemispheres are derived from spheres; dividing a sphere along a great circle results in two hemispheres.

A hemisphere is defined as half of a sphere, typically divided along a great circle, with one flat face and one curved face.

Hemispheres in geography help in understanding Earth's climatic zones, seasonal changes, and time zones.

A sphere is a three-dimensional shape where all points on the surface are equally distant from the center, forming a perfectly round object.

No, hemispheres can refer to any half of a spherical object, including aspects of anatomy like the brain's hemispheres.

No, the formula for a sphere’s volume is (4/3)πr³, while a hemisphere's volume is half that of a sphere.

A sphere exhibits symmetry in all directions, whereas a hemisphere is only symmetrical along the plane that divides it.

Spheres often symbolize wholeness and universality, while hemispheres can represent duality or complementarity in various contexts.

Earth is a sphere, but it can be divided into the Northern and Southern Hemispheres for geographical and climatic studies.

Yes, the concept of a hemisphere can apply to any sphere, including anatomical and astronomical examples.

The flat surface of a hemisphere represents the division of a sphere into two equal halves.

Planets are not perfect spheres due to rotation, which causes an equatorial bulge, making them oblate spheroids.
