The surface area of a sphere is A = 4π R²
The volume of a sphere is V = (4/3) ( π) (R³)
The ratio of (surface area) to (volume) is
4 π R² / (4/3) (π) (R³)
Divide top and bottom by 4π : R² / (1/3) (R³)
Multiply top and bottom by 3: 3 R² / R³
Divide top and bottom by R² : 3 / R .
For the Earth,
A / V = (3) / (3,960 miles) =<em> 0.00076 per mile </em>(rounded)
The graph of this function would be a positive quadratic graph, so a curve with ends that go upwards, with a turning point at the top of the curve at (1, 2).
If we complete the square of this function, we get (x - 1)² + 2, which tells us that the turning point is (1, 2) as to make the bracket equal 0, x has to be 1, and 2 is the only number outside of the bracket.
I hope this helps!
