To find the radius from the circumference, use the formula: `Radius = Circumference / (2 * π)`. Simply divide the circumference by approximately 6.283 (2 times π), and you will get the radius. For example, if the circumference is 31.4 units, the radius will be `31.4 / 6.283 ≈ 5` units.

FAQs & Answers

  1. What is the formula to find radius from circumference? To find the radius, use the formula: Radius = Circumference / (2 * π).
  2. How do you derive the radius from a given circumference? You derive the radius by dividing the circumference value by approximately 6.283, which is 2 times π.
  3. What if my circumference is not a whole number? You can still use the same formula; just ensure you perform the division accurately.
  4. Can I use this method for areas other than circles? This specific method is intended for circles, but similar principles can apply to other shapes with adjustments.
