Pi is the number used to find the circumference or area of a circle. It is also used to calculate the surface area and volume of a sphere, cylinder, and cone.
It can be shortened as 3.14
Numerically it is 3.1415 then a long string of numbers that never end as it is an irrational number. Over 1 million decimal places to the value have been identified. Some folks use 22/7 as a quick value for pi as it is within 0.3% of the correct value.
As to what it is:
Pi ( π) is the ratio between the radius of a circle and its circumfrance. The value allows calculation of the area and circumfrance of a circle and the volume of a sphere.
The number for pi is: 3.1415926535897932384626433832795
several equations' answers come out to 3.14 and so on, thats pi
Pi is important to the study of math because is can be used in many ways. For example, you can use it to find the circumference of a circle and the volume of a sphere. I am not really sure how people calculated that pi works for that, but it plays a big part in our math history.
who invented, or came up with "pi" in math? How did they come up with the estimation of 3.14?

3.14159265 That Pi? Many people use Pi. I use Pi in my math class.
In math terms, pi, means 3.14, which is a everlasting decimal, that is just rounded to make your math easier. So pi, means 3.14 in math terms.

Today is Pi Day in math which is March 14th and the first three digits of pi are 3.14
Pi has undoubtedly contributed to math. Pi can be used for calculating circles and was used to measure distances without doing it the harder way....
you use pi to calculate the area or circumference of a circle
pi... yum (use sign for pi)
