Answer:
System is inconsistent and equations are mutually dependent.
Step-by-step explanation:
Let divide each linear equation by its smallest coefficient:


By using the elimination method on variable x, the following equivalence appears:

Since one of the equation is a multiple of the other one, there is not an unique solution and equations are mutually depedent. The system is inconsistent.
Well, there are two cases in here:
1. The cylinder is at least the same height as its base diameter. The sphere will have the same diameter, which is 2r.
2. The cylinder is short, the height is strictly less than the base diameter. We will denote

.
The volume is
