To find the diameter of a circle, measure the distance across the circle through its center. Alternatively, you can calculate it if you know the radius (diameter = 2 x radius) or the circumference (diameter = circumference/π).

FAQs & Answers

  1. What is the formula to find the diameter of a circle? The diameter can be calculated using the formula: diameter = 2 x radius.
  2. How do I find the diameter from the circumference? To find the diameter from the circumference, use the formula: diameter = circumference / π (pi).
  3. Is the diameter the same as the radius? No, the diameter is twice the length of the radius. The radius is the distance from the center of the circle to its edge.
  4. What tools can I use to measure the diameter of a circle? You can use a ruler or measuring tape to measure across the circle directly, ensuring to do so through the center.
