radius
Center to edge
Radius is the distance from the center of a circle to its edge, or a line segment representing that distance.
By extension, radius describes the area within a certain distance from a point: There are three good restaurants within a one-mile radius.
In anatomy, the radius is one of the two bones in the forearm, running from the elbow to the thumb side of the wrist.
