Get radius from arc length
WebCentral angle = 3 0°. = (θ/360) ⋅ 2Πr. 66 = (30/360) ⋅ 2 ⋅ (22/7) ⋅ r. (66 ⋅ 7 ⋅ 360) / (30 ⋅ 22 ⋅ 2) = r. r = 126 cm. So, the radius of the sector is 126 cm. Example 2 : Find the radius, … 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.
