To find an irrational number between 9 and 11, we can look for a square root of a number that lies between 81 and 121 (since \( 9^2 = 81 \) and \( 11^2 = 121 \)).
Among the options provided, \(\sqrt{99}\) is an irrational number and lies between 9 and 11:
\[ 9 < \sqrt{99} < 11 \]
Thus, the response is: \(\sqrt{99}\) (start root 99 end root).
