In any circle, the ratio of circumference to diameter is (pi).
diameter ------------- Diameter. The R (radius) of a circle multiplied by two equals the diameter.
Circumference = 2*pi*radius or diameter*pi
circumference of a circle = pi*diameter or 2*pi*radius
Divide the circumference by pi.
mutiply by pi 3.14159265.............................................
circumfrance= pi x diameterc= pi x 6c= 18.85
10/pi = 3.1831 feet (rounded)
If that's the diameter, multiply the diameter by pi (which is about 3.1416). If it's the radius, multiply it by (2 x pi).
You multiply the diameter by Pi, that is 3.14159 (to the nearest 5th decimal). circumf. = dia. x Pi.
The number pi is the ratio of the circumference and the diameter of a circle. In Euclidian ("flat") geometry, this ratio is the same for all circles. The number pi is approximately 3.1416. It also has many other uses in mathematics and physics, not all of which have an obvious relation to a circle or sphere.
It is pi
