If a circle has a diameter of 10 cm, what is its radius?

Explanation:
To determine the radius of a circle from its diameter, you simply divide the diameter by 2. The diameter of the circle is given as 10 cm. When you perform the calculation: \[ \text{Radius} = \frac{\text{Diameter}}{2} = \frac{10 \text{ cm}}{2} = 5 \text{ cm} \] This is why the radius of the circle is 5 cm. Understanding this fundamental relationship is crucial in geometry since the radius is always half of the diameter. Hence, the correct choice accurately reflects this principle.
