Which statement best defines the radius of a circle?

Explanation:
The radius is the distance from the center of a circle to any point on its edge. Since the diameter goes from one edge to the opposite edge and passes through the center, it is made of two radii. That means the diameter is twice the radius, so the radius is half the diameter. The other descriptions describe different quantities: the distance around the circle is the circumference, the edge-to-edge length is the diameter, and the area is a measure of space inside the circle, not a length.
