Yes, the radius is half the diameter. The diameter is the full length of a straight line passing through the center of a circle, touching both edges. Therefore, if you divide the diameter by 2, you get the radius. For example, if the diameter is 10 units, the radius would be 5 units.

FAQs & Answers

  1. What is the definition of radius in a circle? The radius of a circle is the distance from the center to any point on the circumference.
  2. How do you calculate the diameter from the radius? To calculate the diameter, simply multiply the radius by 2.
  3. Is the diameter always larger than the radius? Yes, the diameter is always larger than the radius because it is twice the length of the radius.
  4. What are some real-life examples of circles? Common real-life examples include wheels, coins, and round tables.
