Answer:
11.3097335 seems to have nothing with the question so the answer is
B) 18.8495559
Step-by-step explanation:
to find the perimeter (circumference?) do 2pi(r)
2 pi 3 = pi 6 = 18.8495559
since there is 40 percent missing, multiply the perimeter by 60% (part not missing)
18.8495559 * 60%
11.3097335
Answer:
D
Step-by-step explanation:
As you can see from the image attached below, the equation that is being graphed is
F(x) = 
This equation splits off into various directions because the denominator is turns into a quadratic equation. Once solved it provides two values for which the quadratic equation would equal zero. Since this equation is the denominator 0 would give a null value and is why on the graph there is no y value for 1 or -4. Yet all other values are valid and have an different y output.
