Answer:
No units
Step-by-step explanation:
The cost function is given by;

To find the units manufactured at a cost of $5,560
We equate the C(x) to 5560 and solve for x.



The discriminant of this equation is negative.
That is,

Hence the equation has no real roots.
This means no units can be produced at $5,560
It should be 18.84. To find the circumference of a circle you would times the diameter by pi or 3.14 but since its the radius you would need to times pi (by the radius and times that by 2. so 3 times 2 is 6 and 6 times 3.14 is 18.84
