Answer:

275 ft

Step-by-step explanation:

Substituting the values into the formula,

l  = 500pi ft^2-(15ft)^2pi/pi

l = 500ft^2-225ft^2 = 275

Answer:

275 ft

Step-by-step explanation:

[tex]l=\frac{S-\pi r^{2} }{\pi }[/tex] where S = 500πft², r = 15ft

[tex]l= \frac{500\pi -\pi 15^{2}}{\pi }[/tex]

[tex]l=\frac{\pi (500-15^{2}) }{\pi }[/tex]

[tex]l=500-225=275ft[/tex]
