Most calculators use the rounded-off version of pi, which is 3.14159265 (eight significant digits are more than most math problems will require).
several equations' answers come out to 3.14 and so on, thats pi
Oh, dude, it's like basic math, right? If you add pie to pie, you get... drumroll, please... two pies! I mean, who wouldn't want double the pie, am I right? It's simple math, like 1 + 1 = 2, but tastier.
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.
I'm guessing you mean 20 ft. circumference? With a 20' circumference, here's the math. C=20; C(r)=2*[pi]*r; 2*[pi]*r=20; r=10/[pi] A(r)=r2*[pi]; A=(10/[pi])2*[pi]; A= about 31.831 sq. ft.
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)
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.
Pi is when you multiply the diameter in a circle times 3.14. 3.14 = pi.
Pi=3.14 in basic math

If you mean behind a person's name it means Private Investigator. If you are referring to math PI=3.14159265359 ...
It isn't clear what you mean. I don't think that "pi form" is a commonly used math term.
That's the formula for the area of a circle.
It means a rotation of pi radians (180 degrees).
