To find the diameter of a circle, you can use the formula: Diameter = 2 * Radius. Measure the radius, which is the distance from the center of the circle to any point on its edge. Then, multiply that value by 2. For instance, if the radius is 5 cm, the diameter is 10 cm. This simple formula allows you to easily calculate the diameter whenever you have the circle's radius.
