Understanding Circle Radius
The radius is a fundamental measurement of a circle, representing the distance from the center point to any point on the circle's edge. It's essential for calculating various circle properties:
Key Relationships
- Diameter = 2 × Radius
- Circumference = 2 × π × Radius
- Area = π × Radius²
