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. WebCircumference = Diameter x π. π = Pi = 3.14, thus, the math to calculate the circumference of a circle with a diameter of 8 is: 8 x 3.14 = 25.12. And the answer to the circumference of a circle with a diameter of 8 is approximately: ≈ 25.12. We shortened Pi to two decimal points which is why the answer is just approximate.
