To easily find the diameter of a circle, measure the distance across the circle through its center. If you only have the radius, multiply it by two. For instance, if the radius is 5 cm, the diameter would be 10 cm. This is a quick way to determine the diameter with minimal tools.

FAQs & Answers

  1. What is the formula for calculating the diameter of a circle? The diameter is calculated by multiplying the radius by two (D = 2r).
  2. How can I measure the diameter without a ruler? Use a piece of string to measure across the circle and then measure the string with a ruler.
  3. What is the relationship between diameter and circumference? The circumference is calculated using the formula C = πD, where D is the diameter.
