Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.

Since pi is irrational , so the answer is infinity.

the answer is Pi times the square root of a negative number

No. The square root of 9 is 3. An irrational number is a number that can't be expressed with a fraction, meaning it is not an integer or a whole number. Numbers such as pi or e are irrational. Rational numbers are numbers that can be expressed with a fraction. Hope this helps!

Any irrational number added to 0.5 will produce an irrational number.

3 times pi is an irrational number because it can't be expressed as a fraction

No; since pi is irrational if you multiply it by a rational number it is still irrational

No, 3 is a rational number. Pi and the square root of 2 are irrational numbers.

Yes, an irrational number divided by an irrational number will usually be an irrational number, but not always. For example, pi / (3pi) is 1/3, which is a rational number, but pi/e is an irrational number.

there is probably not one

Yes if the diameter is rational. But it need not be if the diameter is irrational. If the diameter is 3/pi units, for example, then the circumference will be (3/pi)*pi = 3 units.

rational because you can simplify the square root to 3 which is the quotient. Pi is probably the most well known irrational number out there. Improved Answer:- Pi is an irrational number because like all irrational numbers they can't be expressed as fractions.

In ancient times the value of Pi was given as 3 but even today the exact value of Pi is not known because it is an irrational number.

Pi is an irrational number. A rational number is one that can be expressed as a fraction (or ratio), e.g. 1/3. There are fractions that are near Pi, for example: 22/7 = 3.142857 (PI = 3.14159265...) A closer fraction is: 355/113 = 3.14159292 However whatever fraction you have, you will never get exactly PI. Hence it is irrational See the links for proofs that pi is irrational.
