The radius of a circle is _______________ its diameter.

Answer

To solve the question, "The radius of a circle is _______________ its diameter," we can follow these steps:

### Step 1: Understand the Definitions
- **Radius**: The distance from the center of the circle to any point on its circumference.
- **Diameter**: The distance across the circle through its center, which is twice the length of the radius.

### Step 2: Establish the Relationship
- The diameter of a circle is made up of two radii. Therefore, if you have one radius, you can find the diameter by doubling that length.

### Step 3: Formulate the Answer
- Since the radius is half the length of the diameter, we can conclude that:
\[ \text{Radius} = \frac{1}{2} \times \text{Diameter} \]
- This means that the radius of a circle is half of its diameter.

### Final Answer
The radius of a circle is **half of** its diameter.
