Answer:
The given expression can't be expressed in polynomial form. Hence, it is not a polynomial.
Step-by-step explanation:
P(x,n) is a polynomial of nth degree if it is of the form,
P(x,n) = 
where n is a finite positive integer and n ∈ N
and '
's are fixed but otherwise arbitrary constants ∀ i = 0(1)n .
Now, the given expression is,

which doesn't fit in the above form. Hence, it is not a polynomial.
Answer:
or 
Step-by-step explanation:
The volume of a cylinder can be found with the following formula:

Where "r" is the radius and "h" is the height of the cylinder.
In this case, let be:
-
the volume of one of this cylinders and
the volume of the other one.
-
the radius of the first one and
the radius of the other cylinder.
-
the height of one of them and
the height of the other cylinder.
Then:

Therefore, you know this:

Simplifying, you get:

Now, knowing the ratios given in the exercise, you can substitute them into the equation:

Evaluating, you get:
