Answer:
To find the volume of a cylindrical water tank, we can use the formula:
Volume = π * r^2 * h
where π is a constant approximately equal to 3.14, r is the radius of the tank, and h is the height of the tank.
1. Find the radius:
- The diameter of the tank is given as 11ft, and we know that the radius is half the diameter.
- Divide the diameter by 2 to find the radius.
Radius = 11ft / 2 = 5.5ft
2. Calculate the volume:
- Substitute the values of π, r, and h into the formula to find the volume.
Volume = 3.14 * (5.5ft)^2 * 8ft
Simplifying further, we get: Volume ≈ 3.14 * 30.25ft^2 * 8ft
Volume ≈ 3.14 * 242ft^3
Volume ≈ 760.28ft^3
3. Round the answer:
- The question asks us to round the answer to the nearest whole number.
- Since the calculated volume is 760.28ft^3, rounding to the nearest whole number gives us:
Volume ≈ 760ft^3
Therefore, the volume of the cylindrical water tank, with a diameter of 11ft and a height of 8ft, is approximately 760 cubic feet.
