WebCircumference = π × Diameter Example: You walk around a circle which has a diameter of 100m, how far have you walked? Distance walked = Circumference = π × 100m = 314m (to the nearest m) Also note that the Diameter is twice the Radius: Diameter = 2 × Radius And so this is also true: Circumference = 2 × π × Radius In Summary: Remembering WebThe formula for circumference using the diameter is, in fact, a lot simpler: C = πd In this formula, C refers to the circumference of the circle while d refers to the diameter of the circle. Simply put, you can solve for the circumference of a circle by multiplying the value of the diameter by the constant value of pi.
