Meaning of "radius" in English

The term "radius" refers to the line segment from the center of a circle or sphere to its perimeter, or boundary. In a geometrical context, it defines half the diameter and is crucial for calculations involving area and circumference. The concept of radius extends beyond just circles to include any radial symmetry in nature or design. Additionally, it is applicable in various scientific fields such as physics and engineering, where it may describe the distance from a central point in mechanisms or field of influence.
