How to Calculate Circle Radius

You can calculate the radius of a circle using the following information:

  1. If the diameter (d) is available in the data, you can calculate the radius using the following formula:
    Radius = Diameter / 2
  2. If the circumference (C) value is available, you can calculate the radius using the formula:
    Radius = Circumference / (2 × π)
  3. If the area (A) value is available, you can calculate the radius using the formula:
    Radius = √(Area / π)
