Answer:
you can put anything to replace x that is greater or equal to 84.
For example:
It just has to be greater or equal to 84.
> = greater than
< = less than
≥ = greater than or equal to
≤ = less than or equal to
Hope this helpss! :)

Explanation:
Perform the necessary mathematics to isolate and solve for
z
while keeping the inequality balanced:
First, expand the terms within parentheis:
16
≥
(
4
⋅
z
)
−
(
4
⋅
7
)
16
≥
4
z
−
28
Next, add 28 to both sides of the inequality:
16

28
≥

z
−
28

44
≥

Then, divide each side of the inequality by 4:
44

Finally, "flip" the inequality to put the answer in terms of
z

First off, the formula for finding the volume of a cylinder is: V=pi × radius² × height
So, because the diameter is 8 inches, to find radius, we just divide by 2 so R=8÷2=4. The radius is 4 inches.
Then because it said that the height is 3 times the radius, 3×4=12. The height is 12 inches.
Now, we can plug in our information and use the formula to find the volume (V=pi × r² × h) :
V= 3.14×4²×12
=3.14×16×12
=608.88 cubic cm ( it can also be written 608.88 cm³)
And there you have the volume. (If this is wrong, then I apologize. I'm pretty sure it's correct tho. If it is wrong, I'll be happy to try to solve it again for you.)
