The value of pi is widely accepted as approximately 3.14; however, as is true of all irrational numbers, when pi is expressed as a decimal, it has an infinite number of decimal places. To see pi expressed beyond its standard approximation, then please refer to the Related Link below.
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".
If you divide the circumference of your noggin by Pi, that will be a pretty good approximation of your hat size.
pi to 5 decimal places = 3.14159
Divide the circumference by pi (pi = 3.14159 or rounded to 3.14 for rough approximation) to find the diameter of a circle.
There is no finite-length decimal number for pi. The decimal for pi goes on until infinity! The most commonly used approximation is 3.14
3.142 rounded to 3 decimal places
That's an approximation of "pi", truncated after ten decimal places.
Yes. That's a decimal approximation of 1 over pi.
It looks like the decimal value of Pi - however, some of the digits are wrong... 3.14159265358979
Pi by definition is simply the ratio C/D = pi where C = 62.8 in and D = 20 in. Plug in the numbers and you can get a value out as far in decimal points as you wish. And that's pi, not an approximation of pi.
An approximation of pi is 3.14159568. It is a non-repeating decimal, and many powerful computers have calculated trillions of decimal places, so the known number is too large for this space.
You can only express this exactly by leaving it as is: 22/7 times pi. If you want a decimal approximation, use an approximation of pi, for example. 3.1416, and do the calculation on a calculator.
Not exactly. To 2 decimal places, pi is 3.14 To 7 decimal places, pi is 3.1415927 To 9 decimal places, pi is 3.141592654 pi does not terminate - it can be expressed to as many decimal places as required. 3.14 is often used as an approximation when doing calculations as it's easier to work with (than 3.141592653... ).
No, but it's a relatively close approximation. 22/7 rounded to six decimal places is 3.142857, whereas pi is 3.141593. ---- 22/7 is only correct to 2 decimal places. A better approximation is 355/113 which is correct to 6 decimal places. 355/113 = 3.141592920353... π = 3.141592653589793... If you need to do accurate calculations involving pi you should use the π (pi) key on a calculator.
Think of pi as infinity. It never ends. You might mean "3.14" as an approximation of pi, though.
