The Formula Explained

The formula to calculate the radius (r) from the circumference (C) is:

  • r = C / (2Ï€)

Where:

  • C is the circumference of the circle.
  • Ï€ (pi) is approximately 3.14159.

Step-by-Step Calculation

  1. Measure the Circumference: Obtain the circumference of the circle. This might be given in the problem or measured directly.
  2. Divide by 2π: Divide the circumference by 2 times π (approximately 6.28318).
  3. Result: The result is the radius of the circle.

For example, if the circumference of a circle is 25 inches:

r = 25 / (2 * 3.14159) ≈ 3.9788 inches
