Final answer:
The volume of the cylindrical water tank is approximately 863 ft³.
Step-by-step explanation:
To find the volume of a cylindrical water tank, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. The diameter of the tank is given as 10 ft, so the radius would be half of that, or 5 ft. The height is given as 11 ft. Plugging in these values, we get:
V = 3.14 × (5 ft)² × 11 ft
Simplifying this calculation, we have:
V = 3.14 × 25 ft² × 11 ft
V = 3.14 × 275 ft³
Rounding to the nearest whole number, the volume of the tank is approximately 863 ft³.
