A 130-degree radius typically refers to a circular arc or sector with a central angle of 130 degrees. In this context, the radius is the distance from the center of the circle to any point on its circumference. This means that if you were to draw a circle with a radius of a specific length, the arc defined by a 130-degree angle would represent a portion of that circle, covering about one-third of its total circumference.
The radius is: 6.267 cm
The total circumference is (arc length) times (360) divided by (the angle degrees)
