Real numbers which cannot be written in (a/b) form are called as Irrational Numbers like √3, √5,√2 etc. Now, we discuss applications of irrational numbers:
1. Use of pi(π) : pi is an irrational number which is use in many purpose in math like:
Area of circle = π * r2 where pi (π) = 3.14 and r is a radius.
Circumference of circle = π * d where d is a diameter of circle,
2. Use of exponential (e): e is an irrational number which is used in many parts of math-.
3. Use of cube root: cube root is basically used to find out area and perimeter of cube and cuboids because both have three dimension structures.
4. Use of irrational number to find out domain: irrational numbers are use to find out domain of particular function. For instance, domain of a function lies between 2 and 3 then we can represent them as √5. Similarly when domain lie between 1 and 2 then we represent them as √2 and between 3 and 4, we can represent them as √11 etc.
So, irrational numbers are used in finding approx value of any real measurement because it is difficult to find out exact value of real measurement. Irrational numbers are calculating non terminating point of function.

The square root of 2 and the value of pi are two examples of irrational numbers which can't be expressed as fractions
Perhaps the best know application is the use of Pi in relation to circles and spheres
They are irrational numbers!
They are numbers that are infinite
Irrational numbers are real numbers.
properties of irrational numbers
No. Some negative numbers are irrational and some are not. Some irrational numbers are negative and some are not.
Numbers that can't be expressed as fractions are irrational
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
No. Irrational numbers are real numbers, therefore it is not imaginary.
Yes, no irrational numbers are whole numbers.
All irrational numbers are real, but not all real numbers are irrational.
