Answer:
Step-by-step explanation:
[tex]Length = 471\:ft\\radius = 10\:ft\\\\L = \frac{\alpha }{360} \times 2\pi r\\\\471 = \frac{x}{360} \times 2 \times 3.14 \times 10\\ \\471 = \frac{x}{360 } \times 62.8\\Cross\:Multiply\\\\471 \times 360 = 62.8x\\169560 = 62.8x \\\\\frac{169560}{62.8} = \frac{62.8x}{62.8} \\\\2700\° = x[/tex]
