Yes, the diameter is exactly double the radius. In geometry, the radius is the distance from the center to the edge of a circle, while the diameter stretches across the entire circle, passing through the center, making it twice the length of the radius.

FAQs & Answers

  1. What is the formula to calculate the diameter from the radius? The formula to calculate the diameter is Diameter = 2 x Radius.
  2. How do you measure the radius of a circle? To measure the radius, find the distance from the center of the circle to any point on its edge.
  3. Can the diameter be used to find the area of a circle? Yes, the diameter can be used; first, divide it by 2 to find the radius, then use the formula Area = π × r².
