Pi is not a variable. Pi is an irrational real positive number. The value of pi is approximately 3.14159
irrational means there is no way to write the exact value of pi. It can not be written with a finite number of decimal points. It can not be written as a fraction. it can not be written as the nth root of any number.
real means it is not generated by taking the square root of a negative number and it is not generated by dividing anything by 0 .
positive means it is greater then 0.

If the perimeter is 20 what is the highest area you can get?
A circle, radius 10/pi has an area of pi x 10/pi x 10/pi ie 100pi/pi2 ie 100/pi ie 31.8; A square 5 to the side has an area of 25.
Is the symbol pi considered a variable in math?
No. It is a constant. A variable is something that changes value in certain circumstances; pi always has the same value.
A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.

Is pi a coefficient?
Yes--in that it is a constant that typically precedes a variable.
