The radius of a circle is half of its diameter.
Given that the diameter of the device is 4.5 inches, the radius is:
\[
\text{Radius} = \frac{\text{Diameter}}{2} = \frac{4.5 \text{ inches}}{2} = 2.25 \text{ inches}
\]
Therefore, the correct answer is **2.25 inches**.
Given that the diameter of the device is 4.5 inches, the radius is:
\[
\text{Radius} = \frac{\text{Diameter}}{2} = \frac{4.5 \text{ inches}}{2} = 2.25 \text{ inches}
\]
Therefore, the correct answer is **2.25 inches**.
