A school is constructing a cylindrical water tank with a radius of 3.5 m and height of 7 m find the volume of the cylindrical water tank

The volume \( V \) of a cylindrical tank is given by the formula:

\[
V = \pi r^2 h
\]

where:
- \( r = 3.5 \, \text{m} \) (radius of the tank)
- \( h = 7 \, \text{m} \) (height of the tank)
- \( \pi \approx 3.14159 \)

Substituting these values:

\[
V = \pi \times (3.5)^2 \times 7
\]
\[
V = \pi \times 12.25 \times 7
\]
\[
V = \pi \times 85.75
\]
\[
V \approx 3.14159 \times 85.75
\]
\[
V \approx 269.39 \, \text{m}^3
\]

Thus, the volume of the cylindrical water tank is approximately **269.39 cubic meters**.

Here are related questions that may interest you:
1. How would the volume change if the radius were doubled?
2. How much would the volume increase if the height was increased by 50%?
3. What would be the volume in liters instead of cubic meters?
4. How do you calculate the surface area of a cylindrical tank?
5. What is the difference in volume between this tank and one with a radius of 4 m and the same height?

**Tip:** For quick approximations, you can round \( \pi \) to 3.14 for easier calculations in volume and area problems.
