Step 1:
Let me solve this step by step with precise mathematical reasoning:

Step 2:
: Define Diameter and Radius

- Diameter is the length of a straight line passing through the center of a circle and connecting two points on the circle's circumference - Radius is the length from the center of a circle to any point on its circumference

Step 3:
: Relationship Between Diameter and Radius

- $$d$$ represents diameter
- By definition, the radius is HALF the length of the diameter Where:

Step 4:
: Verify the Relationship

- $$10 \div 2 = 5
- If a circle has a diameter of 10 units, its radius would be 5 units - This confirms that the radius is always exactly half the diameter

Final Answer

True The radius is indeed half of a diameter. This is a fundamental geometric relationship that holds true for all circles.
