Circumference with radius formula
WebAnswer: Radius = 4 in., diameter = 8 in., circumference =25.12 in. Diameter = 6 feet (as shown in the above picture) The diameter is always twice as long as the radius. So, if our diameter is 6 feet, the radius must be half as long as that. 6 ÷ 2 = 3 So the radius is 3 feet long. For the circumference, we need to choose a 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
