Circumference with radius formula

WebCircumference / Perimeter = 2πr units where r is the radius of the circle. π, read as ‘pi’ is defined as the ratio of the circumference of a circle to its diameter. This ratio is the same for every circle. Consider a circle with radius ‘r’ and circumference ‘C’. For this circle π = Circumference/Diameter π = C/2r C = 2πr WebMar 27, 2024 · Find the circumference of the circle using the radius. There are 2 formulas to find circumference (C). The first is C = πD, where D is the diameter. Multiply the radius by 2 to find the diameter. The second is C = 2πR. Multiply 3.14 by 2, then multiply it by the radius. Both formulas give you the same result.
