How would you find the radius if only the diameter was given?

To find the radius of a circle if only the diameter is given, you simply divide the diameter by 2.

### Formula:
\[
\text{Radius} = \frac{\text{Diameter}}{2}
\]

### Example:
If the diameter \(D\) is 12 units (as calculated from the previous problem):

\[
\text{Radius} = \frac{12}{2} = 6 \text{ units}
\]

### Conclusion:
The radius is half the length of the diameter.
