This a dang easy question. Ask yourself,what is the sentence about?
In cylindrical coordinates, we have , so that
correspond to the upper and lower halves of a sphere with radius . In spherical coordinates, this sphere is .
means our region is between two cylinders with radius 1 and . In spherical coordinates, the inner cylinder has equation
This cylinder meets the sphere when
which occurs at
where . Then .
The volume element transforms to
Putting everything together, we have
Graph #1: No
Graph #2: Yes
Graph #3: No
Graph #4: No
Graph #5: No
Graph #6: Yes
Reasoning:
The vertical line test is a test that determines wether a graph is a function or a relation. The vertical line test shows that if you construct a vertical line through any point on the graph, then the vertical line should only intercept the graph once for it to be a function.
