Looks like we're given

which in three dimensions could be expressed as

and this has curl

which confirms the two-dimensional curl is 0.
It also looks like the region
is the disk
. Green's theorem says the integral of
along the boundary of
is equal to the integral of the two-dimensional curl of
over the interior of
:

which we know to be 0, since the curl itself is 0. To verify this, we can parameterize the boundary of
by


with
. Then


Answer:
-38
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
54/6=9 meaning each face has an area of 9.
Meaning each side has an area of 3.
That means the volume is 3*3*3=27
