Failure. Why we fail, How we fail. Who thinks we fail. and how it leads to success even though we don't know if we're really successful.
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
This would be an example of primary reinforcement
