Ashley Liu 5 years ago Why does every radius in a circle has the same length? I don't get that and its really confusing. • ( 10 votes) catlynx18 9 months ago WebSep 29, 2024 · There are two formulas that can be used to calculate the circumference of a circle: C = 2πr or C = πd, where π is the mathematical constant approximately equal to 3.14, [4] r is equal to the radius, and d is equal to the diameter. [5] Because the radius of a circle is equal to twice its diameter, these equations are essentially the same.

WebThe formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle This is typically written as C = πd. This tells us that the circumference … 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
