Answer:

Step-by-step explanation:
We have to calculate the time derivative of T=PV/nR with P and V variable and n and R constants. This is:

What we have to do is the derivative of a product:

Substituting, we have:

where all these values are given since the time derivatives of P and V are their variation rate, using minutes.
We then substitute everything, noticing that already everything is in the same system of units so they cancel out:

And then just calculate:

2/14 in simplest form is 7.
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
we know that
The volume of a cylinder is equal to

where
r is the radius of the base
h is the height of the cylinder
In this problem

For 
<u>Find the value of h</u>


<u>Find the volume of the cylinder</u>


therefore
<u>the answer is</u>
The volume of a cylinder is equal to
