"The Nine Chapters on the Mathematical Art" is an extremely rich ancient Chinese mathematical classic, which contains the following problem: "There is a circular fortress, with a circumference of 38 feet and a height of 11 feet. How much is the volume? The answer is: 2112 cubic feet. The method says: Multiply the circumference by itself, then multiply by the height, and divide by twelve." This description of the circular fortress refers to a cylindrical body, and its volume V is calculated as $\frac{1}{12} \times (\text{the square of the base's circumference} \times \text{height})$. Therefore, the value of $\pi$ in this problem is $\boxed{3}$.
