No, the diameter is not equal to the circumference. The diameter is the distance across a circle through its center, while the circumference is the distance around the circle. They are related by the formula C = πd where C is the circumference and d is the diameter.

FAQs & Answers

  1. How is diameter related to circumference? The diameter is related to the circumference by the formula C = πd, where C is circumference and d is diameter.
  2. What is the formula to calculate the circumference of a circle? The formula to calculate the circumference of a circle is C = πd, where d is the diameter.
  3. Can diameter and circumference be equal? No, the diameter is always smaller than the circumference for any circle.
  4. What is the diameter of a circle with a circumference of 31.4 units? To find the diameter, use the formula d = C/π. So, d = 31.4/π, which is approximately 10 units.
