What is the diameter of a circle with radius 7?

Explanation:
Diameter is twice the radius—that distance across the circle through its center equals 2r. With a radius of seven, multiply by two to get fourteen. So the diameter is fourteen. The other numbers would be different multiples of the radius, not the diameter.
