**Title: Understanding Circle Dimensions**

---

**3.**

This diagram illustrates a circle with a radius of 2.8 feet. The radius is represented by a line extending from the center of the circle to its edge.

**4.**

This diagram depicts a circle with a diameter of 35 kilometers. The diameter is indicated by a line passing through the center of the circle, touching both sides of the circle.

---

**Explanation:**

- **Radius**: The radius of a circle is the distance from the center of the circle to any point on its circumference. It is half of the diameter.
- **Diameter**: The diameter of a circle is the distance across the circle, passing through its center. It is twice the length of the radius.

By understanding these fundamental concepts, measurements involving circles can be more easily calculated and comprehended.
