Perhaps you mean to find the volume under 
? It seems like you have to rely on calculus otherwise (in the case that you indeed mean 
).
Assuming this, note that describes the top half of a sphere with radius 8, which means the volume below this surface over the disk 
is simply half the volume of the sphere. Thus the volume is
Assuming this, note that
Answer:
Option C
Step-by-step explanation:
Let
x ----> the cost of the concert ticket
we know that
The total cost to be no more than $4 Above $80
so
Solve for x
The total cost to be no more than $4 below $80
so
Solve for x
therefore
The inequality that represent this problem is
<u><em>Verify</em></u>
<em>First solution (positive case</em>)
Solve for x
----> is ok
<em>Second solution (negative case)</em>
Multiply by -1 both sides
Solve for x
---> is ok
Remember that
is equivalent to
Because is a absolute value
