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.
