An example of an irrational number between 9 and 11 is π (pi).
To find an irrational number between 9 and 11, we can use the mathematical constant π (pi).
One example would be to take the value of π - 3. This gives us a number between 9 and 11.
Approximately, π is equal to 3.14. So, π - 3 would be approximately 3.14 - 3 = 0.14.
Therefore, 0.14 is an example of an irrational number between 9 and 11.
