150 views

Yes, the diameter of a circle is just double the radius. This relationship can be captured by the formula d = 2r, where 'd' represents the diameter and 'r' stands for the radius. Understanding this basic geometric principle can be useful in various practical applications, such as calculating the size of wheels, pipes, or any circular objects.

FAQs & Answers

  1. What is the formula for calculating the diameter? The formula for calculating the diameter is d = 2r, where d is the diameter and r is the radius.
  2. Why is the relationship between diameter and radius important? This relationship is crucial for accurate measurements in real-world applications, such as engineering and manufacturing.
  3. Can diameter be calculated from circumference? Yes, the diameter can be calculated from the circumference using the formula d = C/π, where C is the circumference.
  4. How do diameter and radius differ in a circle? The radius is half the length of the diameter, essentially measuring from the center of the circle to its edge.
