The radius of a circle is defined as a line segment that joins the center to the boundary of a circle. The length of the radius remains the same from the center to any point on the circumference of the circle. The radius is half the length of the diameter.
The radius of a circle is the distance from the center of the circle to any point on its circumference. It is half the length of the diameter of the circle. Shown below is the radius of the circle. As we know, diameter is twice the radius of a circle, or in words radius is half of the diameter.
The radius of a circle is the distance from the center of the circle to any point on its circumference. The easiest way to find the radius is by dividing the diameter in half.
ra•di•us (ˈreɪ di əs) n., pl. -di•i (-diˌaɪ) -di•us•es. 1. a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. 2. the length of such a line. 3. any radial or radiating part.
Draw a Radius around a map location. Draw a radius circle around a location in Google Maps to show a distance from that point in all directions.
