The circumference of a circle = pi*diameter. 6 feet 3 inches = 6.25 feet, pi*6.25 = 19.63495408 feet or the circumference of the circle is nearly 20 feet.

The diameter is the same as the length, so it is 20 inches. If you meant to say that the circumference was 20 inches, then divide by pi, which is 3.1416 20 / 3.1416 = 6.4 inches

If the circumference of a circle is 20 cm, the diameter will be: 6.37 cm (D = c divided by Pi).

1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.

r = 3.18 inches.
