Answer:
Map Projections. Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.
HOPE THIS WILL HELPFUL TO YOU..
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
That's not a question... this is a waste of someone's time!!
The question being tested is whether or not the human body will produce more red blood cells at higher altitudes.
The hypothesis an athlete would create from this question is that the body will produce more red blood cells at a higher altitude to ensure the pumping of oxygen throughout the body.
