What is the aproximation of pi?
There are lots of approximations for pi. The most common are: 3.14 about 0.05% low 22/7 about 0.04% high 355/113 about 0.0000849% high
What does Pi Pi equals?
Pi equals the circumference of a circle divided by it's diameter. This value is approximately 3.14159265359, but goes on indefinitely. For most sums 3.14 is acceptable, or just use the pi button on a scientific calculator.
What is the approximate number for Pi?
Common approximations are: 3.14, 22/7 and this one, correct to six places, 355/113 which gives 3.141593.
How can pi be found?
Pi= c/dPi equals the circumference of a circle divided by the diameter. If the radius is presented, double the radius to find the diameter.The Wikipedia article in the related link, lists several formulas which have been used to calculate approximations of the number pi.
What is approximations for pie?
If you are talking about "pi", the math constant related to circles, it is exactly 3.14159265358979. Most people use the approximation of 3.14 in calculating the area of a circle, the circumference, or the volume of a sphere. For very rough approximations, use 3. For example, the circumference of a circle is "pi" x diameter. So a 24-inch bike tire is about 72 inches around. The area of a circle is "pi" x radius squared. So a 10-inch pizza gives you about 75 square inches to eat.
What are the two approximations that used for Pi fraction and decimal?
The pi decimal is 3.14 and the fraction is 22/7
What are the different ways you can represent pi as a number?
The only one that I am aware of is the greek letter pi: π. There are many approximations, such as 3.14 or 3.14159 or 22/7. There are many functions whose solutions involve pi and so can be used to calculate pi. There are also many infinite series that converge to pi or some function of pi. Some are given in the attached link. However, these are all approximations to pi.
What is an equivalent answer to pi?
Pi is a unique ratio - therefore there is no exact equivalent. A couple of rough approximations are 22/7 and 25/8.thanks
What are some accurate approximations of pi?
355/113 (3.141529) is better than 22/7 (3.142857)

What was the earliest known reference to pi in history?
The earliest known textually evidenced approximations of PI date from around 1900 BC. They are found in the Egyptian Rhind Papyrus.
Can yo give a list of approximations?
All irrational numbers are approximations. Thus PI and the decimal notation for one third (1/3) are both approximations. Note that the fraction 1/3 is not an approximation, it is precise, but it is not possible to notate precisely using decimal notation because it extends into infinity (0.3333333333...).
What is the diameter of circumference of 8 cm?
circumference = pi x diameter; diameter = circumference/pi = 8/pipi is approximately 3.14You do the math if you want an approximation(There is no rational answer to this question, only approximations.)
What is the approximate number for Pi?

What is the closet fractional approximation for pi?
Pi is an indiscriminated boolean hypothinator, so it cannot be given a truely incomponential denominator. Therefore, as 1/2 = 2/4, Pi = 7/62626Pi That is pure gobbledygook. Since the questioner speaks of approximations, I presume (s)he knows pi is irrational. There is no closest fraction to an irrational number. No matter what fraction you pick, there is a closer one. Fractional approximations to pi are usually (not always) given as a decimal, so what makes sense to ask is what is the closest approximation to pi to a given number of decimals (digits after the decimal point). For example, the closest approximation to pi to 4 decimals is 3.1416.
