2. center at (3, 1), diameter 14 SOLUTION: Since the radius is half the diameter, r = (14) or 7.

**Step-by-step explanation:**

I believe the answer would be about 5.39.

Without the actually predicted values in comparison to the real values it is only possible to give a very likely answer based on their scale:

a) is 25 million off, which sounds bad but when compared to a few billion in population it's not even 1%

b)3 billion is more than half the world population as error: very unlikely

c)154 billion, unlikely that a prediction is off by a factor of ~30

d)same as c

so a) is most likely the solution, but in theory the predictions could be arbitrarily bad (things like negative population, or extreme growths)
