-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
No, but you can add an irrational number and a rational number to give an irrational.For example, 1 + pi is irrational.
It is irrational, just like pi
No. We go with the proof of a counter-example. pi is a well known irrational number. So is 1/pi. Then pi x (1/pi) = 1, a rational number. If you're not convinced that 1/pi is irrational as well, assume that 1/pi is rational, so that 1/pi = p/q, where p and q are integers and q is not 0 (implicitly, p is also not 0). Then pi = q/p, a contradiction to the fact that pi is not a rational number.
No, it is not.

Well, (pi) x (1/pi) = 1 .
yes pi*(1/pi) = 1
1, 2 are rational and square root of 2 and pi are irrational.
No, but you can add an irrational number and a rational number to give an irrational.For example, 1 + pi is irrational.
irrational
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
It is irrational, just like pi
Pi is not rational it is irrational because it does not stop or repeat
Pi is irrational.
It is a rational number
It the radius is r then the area is pi*r*r - which is pi times a rational number. pi is an irrational number, so the multiple of pi and a rational number is irrational.
