WebParts of a Circle. Circumference: The distance once around the circle. It can also be understood as the circle's perimeter. Radius: The distance from the center of the circle to its edge. No matter which direction you measure in, the radius will be the same from any point on the edge of the circle. Web48. In the diagram of circle P, m∠XYZ is 72°. What is the value of x? 108°. Circle P is shown. Tangents X Y and Z Y intersect at point Y outside of the circle to form an angle with measure 72 degrees. The first arc formed has a measure of x degrees, and the second arc has a measure of (360 minus x) degrees. In the diagram of circle P, m∠ ...
