To find an example of an irrational number between 9 and 11, we need to look for a number whose square root is not a whole number or a fraction. We can use the square root function (√) to find such a number.

One way to find an irrational number between 9 and 11 is to take the square root of a non-perfect square within that range. Let's consider 10, which is not a perfect square.

To calculate the square root of 10, we can write it as √10. Using a calculator or a math tool, we find that the square root of 10 is approximately 3.16227766...

Therefore, we can express an irrational number between 9 and 11 as √10, which is approximately 3.16227766.
