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. WebFeb 2, 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm. The area should equal A = π × (8 cm)² = 201.06 cm². To check your results, input the 8 cm diameter in the calculator. The results should also be 50.265 cm and 201.06 cm².
