It isn't clear what you mean. I don't think that "pi form" is a commonly used math term.
What is mean by acting
area of a circle (A), radius of circle(R): A=R^2
It means a rotation of pi radians (180 degrees).
Pi, in mathematical terms, means the number 3.14159. Pi is a never-ending number ( it goes on forever after 3.14159)
The number for pi is: 3.1415926535897932384626433832795
There is no "most complicated math problem" because numbers are infinite. However, on very complicated problem is pi=? because pi is a repeating decimal, it would go on forever. Because of that, we usually sorten pi to 3.1415...
3.14
3.141592653789 etc
half pi is 1/2 x 3.14 = 1.57
pi (literally and i dont mean the eating pie. by pi i mean in math it never ends)
Pi is when you multiply the diameter in a circle times 3.14. 3.14 = pi.
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.
