Understanding Circle Measurements
When discussing circles, two key measurements are important: the radius and the diameter.
Definitions
- Radius: The distance from the center of the circle to any point on its circumference.
- Diameter: The distance across the circle, passing through the center.
Relationship Between Radius and Diameter
To find the diameter, you can use the formula:
- Diameter = 2 × Radius
This means the diameter is always twice the length of the radius.
Application of the Formula
Given that the radius of the circle is 4 cm, we can calculate the diameter as follows:
- Diameter = 2 × 4 cm
- Diameter = 8 cm
Conclusion
Therefore, the diameter of the circle with a radius of 4 cm is 8 cm.
Final Answer
The correct option is (c) 8 cm. This aligns with the mathematical relationship that the diameter is double the radius.
