Sqrt(27.05) is one such number. Its decimal approximation, to the nearest hundredth, is 5.20 - but to the nearest thousandth is is 5.201

Absolutely. Only fractions can be irrational, numerically speaking (people can also be irrational, but that's a different use of the word).
the set of real numbers are the numbers which make the entire number system. they include all the different number systems like integers,rational numbers,irrational numbers,whole numbers & natural numbers.
Any number that can be expressed as a fraction. When converted to decimal, they either give a finite number of places (e.g. 3/8 becomes 0.375) or give a recurring decimal (E.g. 1/3 becomes 0.333333...etc) Irrational numbers include pi, square root of 2 and e.
All sets of numbers have an infinite number of common multiples. The set of common factors is finite, but can have more than one member. It is not possible to include a diagram in our answers,.

Yes. The domain and range can include irrational numbers.
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.

Yes, any positive number is a number that doesn't have a (-) behind it (-20; -23.67; -45.45454...), and is not zero (0). Any repeating number (see 3rd negative example) is irrational, no matter what its sign. Irrational numbers also include numbers (decimals, specifically) that don't repeat, but don't stop. Numbers that don't terminate include pi. Pi, as it is, is proof of a positive irrational number.

-8.0 is a rational number. Irrational numbers are things such as numbers that can't be expressed as a fraction in the a/b form. Such numbers that are irrational include pi, square roots of negative numbers, etc.
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)
No. Fractions do not include irrational numbers. And although there are an infinite number of both rationals and irrationals, there are far more irrational numbers than rationals.
That would be the real numbers.
An irrational number is any real number that cannot be expressed as a ratio of two integers.So yes, an irrational number IS a real number.There is also a set of numbers called transcendental numbers, which includes both real and complex/imaginary numbers. Of this set, all the real numbers are irrational numbers.
All irrational numbers are non-recurring. If a number is recurring, it is rational. Examples of irrational numbers include the square root of 2, most square roots, most cubic roots, most 4th. roots, etc., pi, e, and most calculations involving irrational numbers.
