Answer: The volume of the pipe is 412 cubic feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π x radius² x height (Length in this case)
Replacing with the values given:
V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet (rounded)
In conclusion, the volume of the pipe is 412 cubic feet
Feel free to ask for more if needed or if you did not understand something.
Answer:

Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0.
The derivative of
is
. The derivative of
is
, for example.
The derivative of the ln function:
If we have:

The derivative is

In this problem, we have that:

So
and 
So the derivative to this function is

The answer is x = 4sqrt(11).
Use pythagorean theoram:
c^2 = b^2 + a^2
(24)^2 = (20)^2 + a^2
sqrt((24)^2 - (20)^2)) = a
a = 4sqrt(11)

Answer:
A positive relationship between the inputs and the outputs is one wherein more of one input leads to more of an output. This is also known as a direct relationship. On the other hand a negative relationship is one where more of one input leads to less of another output.
