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.
Circumference = 2*pi*radius or diameter*pi
it is the circumfrance of a circle divided by pi.
In any circle, the ratio of circumference to diameter is (pi).
Divide the circumference by pi.
yes
mutiply by pi 3.14159265.............................................
circumference of a circle = pi*diameter or 2*pi*radius
circumfrance= pi x diameterc= pi x 6c= 18.85
circumference = 2*pi*5
multiply the radius by two then pultiply that by pi
10/pi = 3.1831 feet (rounded)
Yes. Some examples of formulas that contain pi (∏) are: (area of a circle) = ∏r2 (Circumfrance of a circle) = ∏d
