Solution Steps

Step 1: Identify the given information

The problem provides the diameter of the circle, which is 21 inches.

Step 2: Understand the relationship between diameter and radius

The radius of a circle is half of its diameter. This relationship can be expressed as: \[ \text{Radius} = \frac{\text{Diameter}}{2} \]

Step 3: Calculate the radius

Using the given diameter of 21 inches: \[ \text{Radius} = \frac{21 \text{ inches}}{2} = 10.5 \text{ inches} \]

Final Answer

The radius of the circle is 10.5 inches.
