### Random information on the term “Sphere”:

In geometry, a spherical cap, spherical dome, or spherical segment of one base is a portion of a sphere cut off by a plane. If the plane passes through the center of the sphere, so that the height of the cap is equal to the radius of the sphere, the spherical cap is called a hemisphere.

The volume of the spherical cap and the area of the curved surface may be calculated using combinations of

If ϕ {\displaystyle \phi } denotes the latitude in geographic coordinates, then θ + ϕ = π / 2 = 90 ∘ {\displaystyle \theta +\phi =\pi /2=90^{\circ }\,} .

The relationship between h {\displaystyle h} and r {\displaystyle r} is irrelevant as long as 0 ≤ h ≤ 2 r {\displaystyle 0\leq h\leq 2r} . For example, the red section of the illustration is also a spherical cap for which h > r {\displaystyle h>r} .

### Random information on the term “ORB”:

A sphere (from Greek σφαῖρα—sphaira, “globe, ball”) is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round 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, but in a three-dimensional space. This distance r is the radius of the ball, which is made up from all points with a distance less than (or, for a closed ball, less than or equal to) r from the given point, which is the center of the mathematical ball. These are also referred to as the radius and center of the sphere, respectively. The longest straight line segment through the ball, connecting two points of the sphere, passes through the center and its length is thus twice the radius; it is a diameter of both the sphere and its ball.
