Here you go! Hope this helps!
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>
He paid him : 24t + 15
for 3 hrs...
24(3) + 15 = 72 + 15 = $ 87
X= -10 I hoped this helped you answer your question!
