WebFeb 2, 2024 · 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.

Now, for this, the circumference is 2pir by defenition And the angle is 2 radians. Of course the full angle all the way around is 2pi. So if we call the arc length S that gives us S/ (2pir) = 2/2pi.
