Pi (π) is the ratio of the diameter of circle to its circumference that is used to calculate with circles. Pi=3.14...
The exact value of pi is not known although it has been calculated to several million decimal places.
Pi is used for finding a circumference and area of a circle, the volume and surface area of a cylinder, and many other things.

answ2. Pi is an irrational number, the ratio of the circumference of a circle to its radius. It is universally used in matters circular.
Some people use the computation of pi to a certain number of digits to compare 'computing power' of computers.

What are 3 uses of pi?
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
What formulas use Pi in the equation?
a formula that uses pi is the circumference and area of a circle and every polyhedron that has a circle
What formulas use pi?
the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade
How and when do you use pi in school?
Some of its uses and applications are as follows:- Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius2 Volume of a sphere: 4/3*pi*radius3 Surface area of a sphere: 4*pi*radius2 Volume of a cone: 1/3*pi*radius2*height Curved surface area of a cone: pi*radius*slant length Volume of a cylinder: pi*radius2*height Entire surface area of a cylinder: (2*pi*radius2)+(diameter*pi*height) Pi is the value of a circle's circumference divided by its diameter Pi is the 16th letter of the Greek alpabet
What is the theory of relativity of pi?
Pi is only constant in Euclidean Geometry, it is not the same in other Geometries. In the non-Euclidean geometry that Relativity theory uses the difference between PiE and PiNE is extremely small, approaching zero.
