The best known irrational number is Pi, so, any formula with that in it it, like the formula for

circumference of a circle - Pi * D
area of a circle - Pi * R^2
volume of a sphere - 4/3 * Pi * R^3

Here D and R should be rational numbers, eg integers, to meet your definition.

Are all integers rational numbers

All integers are rational numbers. The easiest way to see that is to write an integer as a fraction with 1 as a denominator; 4=4/1=8/2; 5=5/1.
Any number that can be written as a ratio of two integers numbers is by definition a rational number ( it is a ratio---rational).
Any decimal number with a periodic decimal part can be cast as a fraction, so it is rational.
An irrational number is a number that cannot be written as a fraction.
Examples: PI, sqRT(2), Sqrt(3), SQRT(5), e. There is an infinite number of them.

Define the ff. digits natural # whole # national # irrational # real #??

Sounds like a "school homework" question.

Natural - numbers like 1, 2, 3, 4, ...

Whole - numbers without fractional parts, e.g., '1/2' is not a whole number

National - some countries have superstitions, e.g., American high-rises have no 13th floor,
and some Asian cultures favour street-addresses that contain many '6' characters.

Real - numbers that have a fractional part, e.g., '123.456'.

Rational -- real numbers that can exactly be expressed as a number with a finite-length fraction,
e.g., 1/4, 1/5, 1/8, 1/10, 0.123, 0.45, 0.6.

Irrational -- numbers that cannot be exactly expressed,
e.g. 1/3, 1/7, 1/11, the circumference of a circle divided by its diameter,
no matter how many digits you use.
