A chord or its radius
No. Radius is half of the diameter.
(radius+radius) times pi
You can completely specify a circle in a plane by giving the coordinates of its center point, and the length of the radius.
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

The radius is not named after any person.
Polonium was named after Polonia and radium after radius (ray in the Latin language).
A chord or its radius
Because it was not
A chord or radius. They are both the same. :)
It is not true
The radius bone is so named because of its ability to rotate around the ulna bone, which allows the forearm to rotate. This rotation motion gives the appearance that the radius is "radiating" around the ulna, hence the name "radius."
No, the name radium is derived from the Latin language word radius, equivalent to radiation.

Radius The word radius was a Latin word for the spoke of a wheel. The similarity of radius to the Indo-European root werad from which we get radical and rhizome and the image of the roots of a plant spreading out in all directions like the spokes of a wheel seem too much to resist. Whatever its origin, the word radius was shortened to produce ray, and is also the source of the word radio, named because the electromagnetic rays radiate out in every direction.
The ancient Greek mathematician Pythagoras is usually creditted for the discovery of the ratio of circumference to radius of circles. That is, Circumference = 2 * Pi * Radius. The number Pi represents (3.1415....) is named after him.
Radium was discovered and named in 1898 by Marie Curie, Pierre Curie and Gustave Bemont; the name radium is derived from the Latin language word radius (equivalent to radiation).
