Answer:
[tex]5,890.5\ ft^{2}[/tex]
Step-by-step explanation:
step 1
Find the area that cover each individual head of a sprinkler system
The area of the circle is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=25\ ft[/tex]
assume
[tex]\pi=3.1416[/tex]
substitute
[tex]A=(3.1416)(25)^{2}[/tex]
[tex]A=1,963.5\ ft^{2}[/tex]
step 2
Find the area that covers 3 sprinkler heads
[tex](3)*1,963.5=5,890.5\ ft^{2}[/tex]
