Diameter = circumference/pi

Diameter = circle's circumference/pi

Divide the circumference by pi, and that will give you the diameter.

The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.

circumference = π x diameter π = 3.14159...

You multiply the circle's diameter by 3.14 (Pi) to get the circumference.

Multiply the diameter by pi, and the answer will be the circumference.

Using pi as 3.14, the diameter of the circle is approximately 39.490446

Answer The length around a circle has a special name called circumference. Circumference = pi times diameterThe circumference is the distance around a closed curve. Circumference is a kind of perimeter.The circumference of a circle can be calculated from its diameter using the formula:C = pi times dOr, substituting the diameter for the radius:C = 2 r times piwhere r is the radius and d is the diameter of the circle, and π (the Greek letter pi).Distance around a circle
