The measurement of a circle involves several key concepts and formulas that describe its dimensions. The primary measurements of a circle include: 1. **Radius (r)**: The distance from the center of the circle to any point on its circumference. 2. **Diameter (d)**: The distance across the circle, passing through the center. The diameter is twice the radius: \\\[ d = 2r \\\] 3.
