No, twice the diameter is not a radius. The radius of a circle is half the diameter. So, if you multiply the diameter by two, you get a value that is four times the radius: 2 diameter = 4 radius.

FAQs & Answers

  1. What is the relationship between radius and diameter? The radius is half the diameter of a circle, meaning if you double the radius, you get the diameter.
  2. How do you calculate the circumference of a circle? The circumference can be calculated using the formula C = π * diameter or C = 2 * π * radius.
  3. What is the diameter of a circle? The diameter is the distance across the circle through its center and is twice the length of the radius.
  4. Why is understanding radius and diameter important? Understanding these measurements is essential for solving problems related to circles in geometry and real-world applications.
