There is only one value for Pi. It is 3.1416........... However it can be expressed in two ways. 22/7, or 3.1416.....
Every person who has ever used the "value" of pi in a calculation has used an approximation.
There are no repeating strings of values in pi.
It's a Greek letter. Greek letters are often used to express constants (mathematical values that don't change).
Some common questions about pi include: What is the value of pi? How is pi calculated? Why is pi important in mathematics and science? How many digits of pi have been calculated?
Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.
You can either 1)You can divide out the fraction used for pi then multiply by the diameter or 2)Put the diameter over 1 then multiply across with the fraction used for pi.
infinite number of digits after the decimal point -- pi does not have a finite value.
3.14 is usually what is used for pi, along with 3.1416 which is rounded up. The first two digits are 3.1 and the first two post-decimal values are 1 and 4.
I don't want to try. Pi has been calculated to far higher values than a million decimal places. However more than about forty places have no practical use in the real universe.
To calculate the pI (isoelectric point) value of amino acids, you can use their pKa values. The pI is the pH at which an amino acid carries no net charge. For amino acids with a basic side chain, the pI is the average of the pKa values of the amino and carboxyl groups. For amino acids with an acidic side chain, the pI is the average of the pKa values of the carboxyl and side chain groups.
not sure
Nobody because its a natural fact that the circumference of a circle divided by its diameter is always equal to pi.
