The line from the center of the circle or sphere to its circumference is the radius. Half of the diameter is radius. Consider a bicycle wheel which is of the circle shape. It consists of many spokes. The length of the spoke from the hub to the edge of the wheel is the radius. The radius of the circle based on its circumference can be calculated using this online calculator.
