pi * the golden ratio = 5.08320369

i am not sure what this question asks. both are irrational, but $\phi =\frac{1+\sqrt{5}}{2}$ so it is the solution to a quadratic equation, whereas $\pi$ is not the solution to any polynomial equation (with integer coefficients)

had to google it Phi = 1 - 2 cos ( 3 Pi / 5) robert everest

phi is a historical no.... it sis considered as a golden ratio.. ofcourse other than one of the solutions to a quadratic(that ha sno significance), it is considered the most beautiful no. ever. "1.618" and can be found as a basic for many natural designs, as well in great architectural wonders like the Taj Mahal etc.
