The Circumference of a circle (C) equals the number "pi" times the diameter of the circle (d). "pi" (3.14159...) is a number which you can never find the value of precisely, the numbers after the decimal point go on for ever. Given this information you can calculate what you need to know about your circle.

The diameter of a circle is twice its radius or its largest chord passing through the center of the circle.

It is very close to 7 cm. Circumference = pi (2r) c = 6.2832 r = 44 44/6.2832 = 7.003

-- If you know either the area or the circumference of the circle, you can calculate the other one. -- If you don't know either the area or the circumference, then you have to either measure the circle's diameter, or ask around and try to find someone who already knows what the length of the diameter is. -- Once you have the diameter, take 1/2 of it. That's called the circle's "radius". -- The area of the circle is (pi) x (radius)2 -- The circumference of the circle is (2 pi) x (radius) or (pi) x (diameter). (Pi) is a number that can never be exactly written down, so the best you can do is use some number that's close. The closer your number is to (pi), the closer your answer will be to the truth, but it can never be exactly and perfectly correct. (Pi) is approximately 3.1415926 . But the easiest and most practical way to work with it is to use 22/7 for it. If you do that, then your answers are only about 0.04 percent wrong, and that's actually pretty darn good.

65.97344572538565800766 feet +/- Circumference = Pi x diameter 21 feet x 3.14159265358979323846 = 65.97344572538565800766 feet Of course Pi goes on for many many decimal places so the best we can do is round it off to a point we are satisfied with. Let's call it 65.97 feet.

The ratio of the circumference of a circle to its diameter. Best fit is 355/113, which is correct to 6 places.

The formula for a circumference is 2 times Pi times Radius. A diameter is twice the Radius, so the circumference is Diameter times Pi. 5 times Pi (3.14159) is approximately 15.70795. Pi has an endless number of digits to the right of the decimal point, so the best we can do is approximate.
