correct but please answer to 3 decimal places
1. **State the problem:** Calculate the volume of a tank using the formula given.
2. **Formula used:** 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. **Given values:** Radius $r = 0.5$ m, Height $h = 2$ m.
4. **Substitute values into the formula:**
$$V = \pi \times (0.5)^2 \times 2$$
5. **Calculate the square of the radius:**
$$(0.5)^2 = 0.25$$
6. **Multiply:**
$$V = \pi \times 0.25 \times 2$$
7. **Simplify multiplication:**
$$V = \pi \times 0.5$$
8. **Calculate the volume using $\pi \approx 3.1416$:**
$$V = 3.1416 \times 0.5 = 1.5708$$
9. **Round to 3 decimal places:**
$$V \approx 1.571$$
10. **Final answer:**
The volume of the tank is **1.571 m³**.
