For all circles of all sizes, the length of the circumference divided by the length of the diameter is the same, and this number is the value of pi, which is an irrational number, often it is approximated to 3.14.

What is the formula for the circumstance of a circle where r represents the radius of a circle and c represents the circumstance of a circle.?
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
How do you get a circumference and diameter with pi?
Pi represents the ratio of the circumference of a circle to its diameter. If you know the diameter (D), then the circumference (c) is (D) *pi. If you know the circumference (C), then the diameter (D) is (C)/pi. circumference is 2PiRR is the radius.so 2R is twice the radius (a.k.a. The Diameter)That leaves you withCircumference=Diameter*PiThe circumference can be found by multiplying the diameter by pi, and the diameter can be found by dividing the circumference by pi.
Which represents the volume of a sphere?
The formula for the volume of a sphere is: 4/3*pi*radius^3 measured in cubic units
What does pi in geometry mean?
Pi or π is a constant which represents the ratio of any circles's circumference to its diameter. which is always equal to 22/7 or 3.142any shape that has a curve in it (e.g circle) is related to pi....For example:1.area of a circle= πr22.perimeter of a circle= 2πr
What is the letter which represents the ratio of the circumfernce to the diameter of a circle?
The letter or character used to represent the ratio of the circumference to the diameter of a circle is the Greek lower case letter π, called "pi."
What fraction represents pi?
22/7
Why is pi called a mathimatical constant?
Pi represents a number that cannot be changed, therefore its value is constant.
In math why does pi represent 3.14?
Pi does not represent 3.14. Pi represents the ratio of the circumference of a circle to its diameter. Pi is an irrational number. 3.14 is but the crudest approximation of pi. A better approximation is 3.1416. Still better is 3.14159. The closest approximation commonly used in real-world applilcations is 3.14159262. If anything, 3.14 represents pi, and represents it very imprecisely. As for why the term "pi" was chosen to represent this important concept in mathematics, it was chosen because it is the initial letter of the greek word for "perimeter".

What is the total value of pi?
It is unknown and it usually just represented as pi. It represents the ratio between the circumference and the diameter.
What is the notation for a permutations?
The Greek letter pi. pi(abcd) represents permutations of the letters in the set {a,b,c,d}.
Write the decimal number that represents Pi to 10 places?
3.1428571428
Why is pi a symbol?
Pi is the 16th letter of the Greek alphabet and it represents the value of the circumference of a circle divided by its diameter which is an irrational number.
In statistics what is Pi used for?
In statistics, pi represents the population proportion of successes. Using p, the sample proportion of successes, inferences can be made about pi, although it is usually unknown.
What can you calculate with the formula pi x r2 x g?
