That's the formula for the area of a circle.
Pi is used in the equation to determine the volume of a cylinder with r being the radius and h being the height of the clynder: V = Pi*r2h
Leaving in terms of pi means, through out the whole answer you have the pi symbol when you sub and compute. So basically heres an example: 2pir r=14 2pi14 28pi your answer is 28 with the pi symbol on the right but I dont know how to write it on the computer was that of help?

Radians are measured in terms of pi. Pi = 3.14 (or 180 degrees), so 1 degree = Pi/180 or 0.017 radians. To convert from radians to degrees divide by pi and multiply by 180. For example, 4.71 radians (3Pi/2 in terms of Pi) would be 270 degrees.

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)
pi is a symbol that we all use and it looks something like this....
If you are referring to the number that is used to describe the ratio of a circle's circumference to its diameter, then, yes, in terms of math it is spelled pi. Pi equals out to about 3.141529+ and goes on infinite (never ending).
The number for pi is: 3.1415926535897932384626433832795
3.14
3.141592653789 etc
3.14159265 etc. Correct spelling is: Pi no 'e'
principal(in terms of math)- the amount you borrow or deposit
half pi is 1/2 x 3.14 = 1.57
HL in math mean hypotenuse leg
Pi r 2. Pi is a numerical constant roughly 3.142. r is the radius of a circle. 2 in this case is the square of the radius. All this adds up to the area of a circle. Area=Pi x (radius squared)
