What is the diameter?

Explanation:
Diameter is the distance across a circle through its center; it’s the longest chord and equals twice the radius. Among the options, this is described as the width of a circle—the distance from one side to the opposite side through the middle. The radius is half of that distance, so it’s not the diameter. The circumference is the distance around the circle, and the area is the space inside. For example, if the radius is 3, the diameter is 6.
