Answer:
The answer is [tex](600\pi+1,200)\ ft[/tex] or [tex]3,085\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=\pi D[/tex]
where
D is the diameter of the circle
In this problem, to calculate how many linear feet are needed, find the perimeter of a semicircle
so
[tex]\frac{\pi D}{2}+D[/tex]
we have
[tex]D=1,200\ ft[/tex]
substitute the value
[tex]\frac{\pi (1,200)}{2}+1,200=(600\pi+1,200)\ ft[/tex]
[tex](600\pi+1,200)\ ft=3,085\ ft[/tex]
