To solve for the circumference of a circle, use the formula C = 2πR, where R is the radius. If you know the diameter D instead, use C = πD. This will give you the total length around the circle.

FAQs & Answers

  1. What is the formula for circumference? The formula for circumference is C = 2πR or C = πD, where R is the radius and D is the diameter.
  2. How do you find the circumference if you only have the diameter? Use the formula C = πD, where D is the diameter of the circle.
  3. What is the significance of π in the circumference formula? π (pi) is a constant that represents the ratio of the circumference of any circle to its diameter.
  4. Can circumference be calculated for shapes other than circles? Circumference specifically refers to the distance around a circle; however, similar concepts apply to other shapes like ellipses.
