Exempel på hur man kan använda RADIUS i en mening

• The Earth's radius at the equator in the GRS80 ellipsoid is , which makes the geographical mile 1,855.
• The holographic principle was inspired by the Bekenstein bound of black hole thermodynamics, which conjectures that the maximum entropy in any region scales with the radius , rather than cubed as might be expected.
• The period began with the creation of the London Passenger Transport Board, which covered the County of London and adjacent counties within a 30-mile (48-km) radius.
• It is defined such that one radian is the angle subtended at the centre of a circle by an arc that is equal in length to the radius.
• It is an aging red giant star 90% as massive as the Sun that has cooled and expanded to a radius 54 times greater than it.
• Once the radius is fixed, the three coordinates (r, θ, φ), known as a 3-tuple, provide a coordinate system on a sphere, typically called the spherical polar coordinates.
• In electromagnetics, especially in optics, beam divergence is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the beam emerges.
• The density of flux lines is inversely proportional to the square of the distance from the source because the surface area of a sphere increases with the square of the radius.
• Profiles are drawn either with an effective Earth radius simulated by a parabolic arc--in which case the ray paths are drawn as straight lines--or with a "flat Earth"-- in which case the ray paths are drawn as parabolic arcs.
• If the clearance from the nearest anticipated path position, over the expected range of Earth radius k-factor, exceeds 0.
• Cellular and microwave towers within this radius can reflect the Medium Wave AM signal out at a phase which cancels the main Medium Wave AM signal.
• Radius of gyration or gyradius of a body about the axis of rotation is defined as the radial distance to a point which would have a moment of inertia the same as the body's actual distribution of mass, if the total mass of the body were concentrated there.
• Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude more than about one-third of the radius of Earth (or about 2000 kilometers), roughly at the beginning of the inner Van Allen radiation belt.
• Any diameter of any great circle coincides with a diameter of the sphere, and therefore every great circle is concentric with the sphere and shares the same radius.
• In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth.
• Typically, because of the difficulty to isolate atoms in order to measure their radii separately, atomic radius is measured in a chemically bonded state; however theoretical calculations are simpler when considering atoms in isolation.
• With a radius between 640 and 764 times that of the Sun, if it were at the center of our Solar System, its surface would lie beyond the asteroid belt and it would engulf the orbits of Mercury, Venus, Earth, and Mars.
• In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation.
• The compass is assumed to have no maximum or minimum radius, and is assumed to "collapse" when lifted from the page, so it may not be directly used to transfer distances.
• In mathematics, the radius of convergence of a power series is the radius of the largest disk at the center of the series in which the series converges.
