No, the diameter is not half of the radius. In fact, the diameter of a circle is twice the length of the radius. To put it simply, if you know the radius, you can find the diameter by doubling it: Diameter = 2 × Radius.

FAQs & Answers

  1. Is the radius half of the diameter? Yes, the radius is half of the diameter. You can calculate the radius by dividing the diameter by two: Radius = Diameter ÷ 2.
  2. How do you find the diameter of a circle? To find the diameter of a circle, simply multiply the radius by two: Diameter = 2 × Radius.
  3. What is the relationship between radius and diameter? The radius is the distance from the center of the circle to any point on its circumference, while the diameter is the distance across the circle, passing through the center. The diameter is always twice the length of the radius.
  4. Can you give an example using the diameter and radius? Sure! If the radius of a circle is 5 units, the diameter would be 10 units, since Diameter = 2 × Radius (2 × 5 = 10).
