Yes, the radius of a circle is half the 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. Therefore, the radius is always half the diameter.

FAQs & Answers

  1. What is the formula for calculating the radius of a circle? The radius can be calculated by dividing the diameter by two, or using the formula r = d/2.
  2. Can the radius ever be equal to the diameter? No, the radius is always half the diameter, so they cannot be equal.
  3. How do you find the diameter if you know the radius? To find the diameter, simply multiply the radius by two: d = 2r.
  4. What other properties are important in circle geometry? Other important properties include circumference, area, and the relationship between radius and arcs.
