What is the diameter of a circle with a radius of 7 units?

To determine the diameter of a circle, you can use the relationship between the radius and diameter. The diameter is always twice the length of the radius. This can be expressed with the formula:

Diameter = 2 × Radius.

In this case, the radius is given as 7 units. Using the formula, you would calculate:

Diameter = 2 × 7 = 14 units.

This confirms that the diameter of the circle with a radius of 7 units is indeed 14 units.
