What is the diameter of a circle with radius 7?

Explanation:
Diameter is twice the radius. The radius is the distance from the center to the circle, while the diameter is the straight line through the center that connects two points on the circle—the longest distance across. With a radius of 7, doubling gives 14, so the diameter is 14. The radius itself would be 7, and other options that are multiples of the radius (three times, four times, etc.) exceed the diameter, so they aren’t correct.
