How do you get from circumference to radius
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 WebCircumference and area of a circle ... for any circle, the diameter is twice the radius, or \(d = 2r\). For this circle: ... Our tips from experts and exam survivors will help you through. Get ...
