Solution :
Since, we can measure the height of fluid. Let it be h.
So height of cylinder is double the height i.e. 2h because cylinder is partially filled.
Also, we can also measure diameter. Let it be d.
Now, we know, radius is haft the length of diameter.
So, r = d/2.
Volume of cylinder is given by :

Hence, this is the required solution.
