In math, a value that represents a constant relationship is given a Greek letter to represent it. Examples are epsilon and sigma functions.
The ratio of the circumference to the diameter of a circle is about 3.14159 but can be calculated to an infinite number of places. This was assigned the Greek letter pi (π).

Who named pi?
The Greek letter π, often spelled out pi in text, was adopted for the number from the Greek word for perimeter"περίμετρος", first by William Jones in 1707, and popularized by Leonhard Euler in 1737.
Why is pi named that?
The word "Pi" derives from the letter "P" (π) out of the Greek alphabet, which's the first letter of the word "περιφέρεια" - peripheria meaning periphery, respectively "περίμετρος" - perimetros, Greek for circumference.
What is the cubic root of pi squared multiplied by pi?
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
What is pi plus pi plus pi?
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.
What is the derivative of cos pi x plus sin pi y all to the 8th power equals 44?
(cos(pi x) + sin(pi y) )^8 = 44 differentiate both sides with respect to x 8 ( cos(pi x) + sin (pi y ) )^7 d/dx ( cos(pi x) + sin (pi y) = 0 8 ( cos(pi x) + sin (pi y ) )^7 (-sin (pi x) pi + cos (pi y) pi dy/dx ) = 0 8 ( cos(pi x) + sin (pi y ) )^7 (pi cos(pi y) dy/dx - pi sin (pi x) ) = 0 cos(pi y) dy/dx - pi sin(pi x) = 0 cos(pi y) dy/dx = sin(pi x) dy/dx = sin (pi x) / cos(pi y)
