-2π is an irrational number. While -2 is a rational number, π (pi) is known to be irrational, meaning it cannot be expressed as a fraction of two integers. The product of a nonzero rational number and an irrational number is always irrational, so -2π remains irrational.
In general, no. It is possible though. (2pi)/pi is rational. pi2/pi is irrational. The ratio of two rationals numbers is always rational and the ratio of a rational and an irrational is always irrational.
It depends on the percentage. A 1 cm arc of a circle whose radius is 1 cm will represent 100*1/(2pi) % = 50/pi % and that is an irrational percentage. A semicircular arc of the same circle will represent 50%, which is rational.
No. A rational plus an irrational is always an irrational.
rational
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
NO. pi is an irrational number, therefore, 2pi is also an irrational number/
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
In general, no. It is possible though. (2pi)/pi is rational. pi2/pi is irrational. The ratio of two rationals numbers is always rational and the ratio of a rational and an irrational is always irrational.
No. The number pi is irrational, and if you multiply an irrational number by a non-zero rational number (in this case, -2), you will get another irrational number.As a general guideline, most calculations that involve irrational numbers will again give you an irrational number.
Consider pi and 4 - pi. 4 - pi + pi = 4, which is clearly rational. However, both pi and 4 - pi are irrational, as you can verify. plz to be lerning numburs Then consider pi + pi = 2pi, which is clearly irrational. The sum of two irrational numbers, therefore, may or may not be rational.

4.6 is rational.
Rational
34.5 is RATIONAL. Irrational numbers are those were the decimals go to infinity AND there is no regular order in the decimal numbers. Definitively an Irrational Number CAnnot BE CONVERTED TO A quotient/ratio/frACTION pi = 3.141592.... is the most well known irrational number. So 34.5 is rational 34.55555..... is rational (gOES TO INFINITY ; numbers in regukar order). 34.565656.... is Rational (Goes to infinity ; numbers in regulkar order). et seq., The dots after the number mean it continues to infinity . However, 34.25865414..... is Irrational . Because there is no regular order in the decimal digits.
Rational.
If x is rational the it is rational. If x is irrational then it is irrational.
No. A rational plus an irrational is always an irrational.
