Radius of a Circle Calculator
WebFeb 2, 2024 · To find the radius whose circumference is equal to 6 feet, we follow the steps below: Write the circumference as c = 6 ft. Recall the formula for the radius of a circle from circumference: r = c / (2 * π). Inject the circumference into the equation: r = (6 ft) / (2 * π) = 3/π ft. If needed, substitute π ≈ 3.14: r = 3/π ft ≈ 0.96 ft. WebTo calculate the length (= the arc length) you need to calculate the whole circumference first and then multiply it by 3/4 to find the length you really want: Whole circumference = 2*Pi*radius = 8*Pi = approx. 25.13dm, The length that you need: (8*Pi) * (3/4 ) = 6*Pi = approx. 18.85dm.
