36 views

To find the diameter of a circle if you know the circumference, use the formula: Diameter = Circumference / π (pi). For example, if your circumference is 31.4 units, divide 31.4 by approximately 3.14159 (pi), giving you a diameter of 10 units. This simple division will give you the circle's diameter.
