To determine which circle has a radius that measures 10 units, we follow these steps:
1. Understanding the Measurement: We know that the radius is the distance from the center of the circle to any point on its circumference. It is a key characteristic that defines the size of the circle.
2. Given Radius: The problem specifies that the radius is 10 units.
3. Identifying the Circle: Any circle that has its radius measuring exactly 10 units would satisfy this condition.
Therefore, the answer is simply any circle with a radius of 10 units.
