No, since Pi is an irrational number, 2(pi) would still be irrational.
If you mean Pi as regards to a circle then it is an irrational number
-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.
Pi is an irrational number
Yes, it is an irrational number.
It is irrational, just like pi
A non-zero rational number (10) multiplied by an irrational number (pi) is always irrational.
pi is an irrational number. It is irrational because it cannot be expressed as a ratio of two integers.
The square of pi is an irrational number.
That's the number pi, and yes, it is irrational.
The product of two rational numbers, as in this example, is always RATIONAL.However, if you mean 10 x pi, pi is irrational; the product of a rational and an irrational number is ALWAYS IRRATIONAL, except for the special case in which the rational number is zero.
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.
