Answer:
d. 6
Step-by-step explanation:
A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.
Area of a circle: A = pi x r^2
r = 160 / 2 = 80
A = pi x 80^2
A = 6400pi / 2 = 3200pi
3200pi = 10053.0965
The area water is approximately 10,053 ft^2.
Hope this helps!! :)
From the given statement, we know the following...

So if we solve for x by dividing by 0.35
x = $247/0.35 = $705.71
