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. WebArea of a circle: A = π r 2 = π d 2 /4 Circumference of a circle: C = 2 π r = π d. Circle Calculations: Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable. …

WebThe circumference can be found by the formula C = πd when we know the diameter and C = 2πr when we know the radius, as we do here. Plugging our radius of 3 into the formula, we get C = 6π meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. WebIt's simplest to convert circumference to radius first, then find the circle's area: r = (c/2\pi) \\ a = \pi r^2 r = (c/2π) a = πr2 Using the Circumference Calculator You can enter the circumference and also compute radius and diameter in mils, inches, feet, yards, miles, millimeters, centimeters, meters and kilometers.
