Yes. For example, if you take any truncated equivalent of pi then it will be rational.

0(pi) itself is an irrational number. The only multiples of it that can be rational are (pi) x (a rational number/pi) .

3.14 is a rational number pi is not. pi is not 3.14

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.

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

Minus pi. Or minus pi plus any rational number. Here is how you can figure this out (call your unknown number "x", and let "r" stand for any rational number):x + pi = r To solve for "x", simply subtract pi from both sides. That gives you: x = r - pi

No 10*pi is not a rational number because it can't be expressed as a fraction

No. pi/2 is a faction but it is not a rational number.

Assuming that you mean pi, and not pie, it is not a rational number.The set of rational numbers is a field and this means that for every non-zero rational number, there exists a multiplicative inverse in the setand also, due to closure, the product of any two rational numbers is a rational number.Now suppose 7*pi were rational.7 is rational and so there is its multiplicative inverse, which is (1/7).(1/7) is also rational so (1/7)*(7*pi) is rationalBut by the associative property, this is (1/7*7)*pi = 1*pi = pi.But it has been proven that pi is irrational. Therefore the supposition must be wrong ie 7*pi is not rational.

No 22*pi is not a rational number

Pi as relating to a circle is an irrational number because it can't be expressed as a fraction. It is a real number but it is not rational.No.Pi is considered an Irrational number because its decimals do not repeat or terminate, which are the requirements for a number to be rational (in addition to other things)

No, it is not.

Here is an example sentence with the word "rational":Any number that is recurring is classified as a rationalnumber.And as a bit of a laugh:3.14 to Pi: Be rational!Pi to 3.14: Be real!

It can be rounded to 3.14, this however does not make it a rational number.

Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.

It is irrational, just like pi

no every periodic number is rational but pi is irrational

No, since Pi is an irrational number, 2(pi) would still be irrational.

A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.

No. sqrt(2)/pi is not rational.

No, Pi is an Irrational Number.

No, it is not.

No, it is not.

pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer.pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer.pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer.pi is a transcendental (a special type of irrational) number whereas 3 is not only rational, but an integer.

-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 because 15 times pi is an irrational number
