To convert the radius of a circle to its diameter, multiply the radius by 2. For example, if the radius is 5 units, the diameter will be 10 units (5 * 2). To find the circumference, use the formula C = 2πr, where C is the circumference and r is the radius.**

FAQs & Answers

  1. What is the formula to convert radius to diameter? To convert the radius of a circle to its diameter, simply multiply the radius by 2. For example, if the radius is 5 units, the diameter will be 10 units (5 * 2).
  2. How do you find the circumference of a circle using the radius? The circumference of a circle can be found using the formula C = 2πr, where C is the circumference and r is the radius.
  3. What is the relationship between the radius and diameter of a circle? The diameter of a circle is always twice the length of its radius, meaning that if you know the radius, you can easily calculate the diameter by multiplying it by 2.
  4. Can you explain the difference between radius and diameter? The radius of a circle is the distance from the center to any point on its perimeter, while the diameter is the distance across the circle through the center, which is twice the radius.
