Answer:
27:18.
Step-by-step explanation:
27/9 = 3
18/9 = 2
It would be 16 minutes because you would divide 80 by 20 and you get 4 so now you multiply 4 by 4 and you get 16
Substitution for both equations is (-3,1)
The area is 3.14*r^2
<span>The rotating valve would be in the center of the circular wet patch so if it's spraying in all directions, then 15 ft = radius. </span>
<span>Now plug it in. </span>
<span>3.14 x (15)^2 = 706.5 ft^2</span>
