1. **Problem:** Find the volume of a cylinder with radius $r=11$ m and height $h=22$ m. 2. **Formula:** The volume $V$ of a cylinder is given by $$V=\pi r^2 h$$ where $r$ is the radius and $h$ is the height. 3. **Calculate:** Substitute $r=11$ and $h=22$: $$V=\pi \times 11^2 \times 22$$ $$=\pi \times 121 \times 22$$ $$=\pi \times 2662$$ 4. **Evaluate:** Using $\pi \approx 3.1416$, $$V \approx 3.1416 \times 2662 = 8361.73$$ 5. **Answer:** The volume of the cylinder is approximately **8361.73 cubic meters**. Note: Only the first problem is solved as per instructions.
