It is a combination of numbers and variables, linked together by mathematical functions. For example sqrt(2y/3*7.34*pi) where y is some variable. Given the value(s) of the variable(s) it is possible to evaluate (find the value of) the expression.
It is 2*sqrt(3)/3.
Yes because circumference = diameter*pi and the value of pi is just over 3
30 degrees or pi/6

Cos(Pi/3) is 1/2 so Cos(-Pi/3) ould be flipped over the x-axis. The answer is still 1/2.
It is because that is what the ratio pi is equal to.

sin pi/2 =1 sin 3 pi/2 is negative 1 ( it is in 3rd quadrant where sin is negative
pi squared
tan(pi/3)= sqrt(3)
Yes because circumference = diameter*pi and the value of pi is just over 3
No; since pi is irrational if you multiply it by a rational number it is still irrational
