## Radius

The size of any circle depends on one single parameter that guides it when it is drawn - this is the radius. The radius of a circle, by definition, is the distance from the center of the circle to each point on it. The radius of the circle is directly proportional to the circumference and diameter.

## Sphere

Sphere — a closed surface, all points of which are equally distant from one point (the center of the sphere). A segment connecting the center of a sphere with any point of it (as well as its length) is called the radius of the sphere.

A sphere is a volumetric body of rotation of a circle around its own diameter. Thus, we can assume that almost all units of measure inherent in the circle go over the sphere, including primarily the radius and diameter. In the sphere, the relations of radius and diameter remain the same as in the circle. If in the case of a circle, the radius depends on the circumference and the area of the circle, then the sphere instead of the area has volume, so the radius of the sphere can be calculated through the volume.
