To find the radius with a given circumference, use the formula: `radius = circumference / (2 π)`. For example, if the circumference is 31.4 units, the radius would be `31.4 / (2 π) = 5` units. This straightforward calculation allows you to determine the radius efficiently.

FAQs & Answers

  1. What is the formula for finding the radius from circumference? The formula is radius = circumference / (2π).
  2. How do I use the radius formula for a circle? Simply plug the circumference value into the formula to calculate the radius.
  3. What does circumference mean in geometry? Circumference is the distance around a circle, equivalent to 2π times the radius.
  4. Can this method be used for any circle? Yes, this formula applies to all circles regardless of size.
