Answer/Step-by-step Explanation:
Circumference of a circular object = πd
Where,
π = 3.14,
d = diameter
Circumference of hula pop with diameter of 35 in:
Circumference = πd = 3.14*35 = 109.9 in
Diameter of circular pond with a circumference of 556 ft:
556 = 3.14*d
Divide both sides by 3.14
556/3.14 = d
177.07 = d
d ≈ 117 in
Circumference of magnifying glass with a diameter of 5.2 in:
Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm
Diameter of car tire with a circumference of 71.6 in:
71.6 = 3.14*d
Divide both sides by 3.14
71.6/3.14 = d
22.80 = d
d ≈ 22.8 in

Answer:
c
a
b
Step-by-step explanation:
This is a strange question, and f(x) may not even exist. Why do I say that? Well..
[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).
[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!
Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.
To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.
