175 views

Yes, the circumference is dependent on the diameter. The relationship is straightforward: the circumference (C) is equal to the diameter (D) multiplied by π (pi), which is approximately 3.14159. The formula is C = πD. So, if you know the diameter, you can easily calculate the circumference by multiplying it by π.

FAQs & Answers

  1. What is the formula for calculating circumference? The formula for calculating circumference (C) is C = πD, where D is the diameter of the circle and π (pi) is approximately 3.14159.
  2. How is circumference related to diameter? Circumference is directly proportional to diameter; as the diameter increases, the circumference increases proportionally.
  3. What is the value of pi (π)? Pi (π) is a mathematical constant approximately equal to 3.14159, representing the ratio of the circumference of a circle to its diameter.
  4. Can I calculate circumference without knowing diameter? Yes, if you know the radius (R) of the circle, you can calculate circumference using the formula C = 2πR, since the diameter is twice the radius.
