Answer:
11 ft
Step-by-step explanation:
The radius of the area of the circular pattern = how far the sprinkler cam spread water
Area of the circular watering pattern = 379.94 ft²
Area of circle = πr²
Thus,
πr² = 379.94
Divide both sides by π
r² = 379.94/π
r² = 120.938658
Take the square root of both sides
r = √120.938658
r = 10.9972114 ≈ 11 ft
Water can be spread 11 ft away from the sprinkler
