Circumference = π·d = 3.14·4 = 12.56 (*) In terms of area:. Circumference C = √ 4·π·A = √ 4·π·12.57 = 12.57 (*) (*) 12.57 cm exactly or limited to de precision of this calculator (13 decimal places). Note: for simplicity, the operations above …π = 22 7 or 3.142. r = radius. Hence you can find the radius of the circle from the circumference.. C = 2πr. Divide both sides by 2π. C 2π = 2πr 2π. C 2π = 2πr 2π. C 2π = r. r = C 2π.A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d) Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r). The circumference of a circle is found using this formula: Examples #2. Calculate the circumference of a circle if r = 4 inches. C = 2 × π × r = 2 × 3.14 × 4 = 25.12 inches. Examples #3. If D = 10 centimeters, find the circumference. You have two choices. You can first find r and then substitute its value for r in the formula. r is half the diameter, so r = 10 divided by 2.48. 49. 50. This calculator will calculate the circumference of a circle given its diameter, using the famous formula circumference = pi times d. It supports different units such as meters, feet, and inches. Just type into the box and hit the calculate button. printf("Enter the radius of the circle: "); scanf("%f", &radius); Then, the user is asked to enter the radius of the circle. // Circumference. cf = 2 * PI * radius; We calculate the circumference of the circle using the formula 2πr.
