- n. In mathematics, one of a number of lines proceeding from a center; a ray; especially, a line drawn from the center to the periphery of a circle or sphere; also, the measure of the semidiameter.
- n. In anatomy and zoology, the outer one of the two bones of the forearm, or corresponding part of the fore leg; the bone on the thumb side of the forearm, extending from the humerus to the carpus, and bearing upon its distal end the manus or hand: so called from its revolving, somewhat like a spoke, about the ulna, as in man and other mammals whose fore limb exhibits the motions called pronation and supination.
- n. In ichthyology, a bone of the pectoral arch, wrongly identified by some naturalists with the radius of higher vertebrates. The one so called by Cuvier is the hypercoracoid, and that of Owen is the hypocoracoid.
- n. In entomology, a vein of the wing of some insects, extending from the pterostigma to the tip of the wing.
- n. In conchology, a genus of Ovulidæ. R. volra is the shuttle-shell or weaver-shell.
- n. plural In ornithology, the barbs of the main shaft of a feather; the rays of the first order of the rachis.
- n. In arachnology, one of the radiating lines of a geometrical spider's web, which are connected by a single spiral line.
- n. In echinoderms, one of the five radial pieces of the dentary apparatus of a sea-urchin, being an arched rod-like piece articulated at its base with the inner extremity of each rotula, running more or less nearly parallel with the rotula, and ending in a free bifurcated extremity. Also called the compass of the lantern of Aristotle (which see, under lantern). See also cut B under lantern.
- n. plural Specifically, in Cirripedia, the lateral parts of the shell, as distinguished from the paries, when they overlap: when overlapped by others, they are called alæ.
- n. In botany, a ray, as of a composite flower, etc.
- n. The movable limb or arm of a sextant; also, a similar feature in any other instrument for measuring angles.

The radius, _p b_, of the upper circle is termed the _crater radius_; the line _o p_, drawn from the centre of the charge perpendicular to the surface where the explosion takes place, is termed the _line of least resistance_; the line _o b_, drawn from the centre of the powder to any point in the circumference of the upper circle, is termed the _radius of explosion_.

Indeed, Mars's satellite Phobos, whose mean radius is 11.1 km, has a numerically similar escape velocity of 11.3 metres per second - as you may vaguely remember fron Arthur C. Clarke's story, "Hide-and-Seek".
Since the Earth's radius is around 6400 km, I could probably jump off a celestial body of the Earth's density which had a radius of about 2.7 km or smaller
The moz-border-radius is understood by all mozilla based browsers such as Firefox.
Daniel – not sure what that wide radius is but I can think of two places with good fried foods.
At only 30 feet tall and 2 feet in radius, Windspire is distinguished by its sleek propeller-free design, ultra quiet operation, rugged construction, and affordable pricing.
So we went outside and, lo and behold, about 20 degrees* in radius around the Moon was a nearly complete halo!
And, indeed, I would agree with that ranking, but the only reason we want a sphere of autonomy is because we happen to be sympathetic to ranking freedoms according to their radius from the center of the sphere of autonomy.
Thus the clockwork Earth is (2,575,342/2pi = 409,878 km) in radius (about 64x our Earth's)
