Final answer:
The correct inequality is B. 9 pi > 27.
Step-by-step explanation:
A mathematical inequality is a statement that shows the relationship between two expressions, indicating that one is greater than, less than, or equal to the other. Symbols like < (less than), > (greater than), or ≤ (less than or equal to) are used.
The correct inequality is B. 9 pi > 27.
To determine if this inequality is true, we need to compare the value of 9 times pi to the value of 27.
Pi is approximately 3.14, so when we multiply 9 by pi, we get 9 * 3.14 = 28.26, which is greater than 27.
Therefore, the inequality 9 pi > 27 is true.
