Actually the product of a nonzero rational number and another rational number will always be rational.The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
3 times pi is an irrational number because it can't be expressed as a fraction
If you mean 0.3 times pi then it is an irrational number
75 times 75 = 5625 which is a rational number
Since pi is irrational, its product with any other number is also irrational. The only exception is a multiple of its own reciprocal.
The product of 0 and an irrational is 0 (a rational), the product of a non-zero rational and any irrational is always irrational.
No.A rational times an irrational is never rational. It is always irrational.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Unless the rational number is zero, the answer is irrational.
Not necessarily. 0 times any irrational number is 0 - which is rational.

Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
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.
No; since pi is irrational if you multiply it by a rational number it is still irrational
Any multiple of or addition to or subtraction from PI is an irrational number. PI divided by PI is 1, a rational number. So is PI times 0 = 0
Well, (pi) x (1/pi) = 1 .
No because 15 times pi is an irrational number
