Yes, doubling the radius of a circle also doubles the diameter. Since the diameter is twice the radius (D = 2r), if the radius doubles, the new diameter becomes 2 times the new radius, maintaining the relationship.

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 D = 2r, where D is the diameter and r is the radius.
  2. If the radius is tripled, how does that affect the diameter? If the radius is tripled, the diameter also triples, following the same rule that the diameter is always twice the radius.
  3. What are some real-world applications of radius and diameter? Radius and diameter calculations are used in various fields, including engineering, architecture, and manufacturing, to determine sizes and measurements of circular objects.
  4. Can you explain the difference between radius and diameter? The radius is the distance from the center of the circle to its edge, while the diameter is the distance across the circle through its center, equal to two times the radius.
