Yes, the radius is half of the diameter. For any circle, the diameter is the total distance across the circle through its center, whereas the radius is the distance from the center of the circle to any point on its edge. So, if you know the diameter of a circle, simply divide it by two to get the radius.

FAQs & Answers

  1. What is the formula for calculating the diameter of a circle? The diameter of a circle can be calculated using the formula: Diameter = 2 x Radius.
  2. How do you find the radius if you only have the diameter? To find the radius from the diameter, simply divide the diameter by two: Radius = Diameter / 2.
  3. What are the main properties of a circle? The main properties of a circle include the radius, diameter, circumference, and area.
  4. What is the relationship between radius and diameter? The radius is always half of the diameter in any circle, defining the circle's size.
