So use half the surface area formula: SA=2πr^2 and plug in what you already know
since you don't know the radius yet, solve for it using the circumference
C=2πr
514.96=3.14(2)r
82=r
SA=2π(82)^2
SA=6.28(6724)
SA=42,226.72
so your answer is 42,226.72 yards squared
E Both A & C, need an explanation?
State , because the state owner , mayor wtv it is , shouldn’t take care of his state , it isn’t a federal problem
