Answer:
3x+8y=-5-equatin.1
-2x+2y=18-equation.2
now,
subtracting both equation.1 by equation.2,then
3x+8y=-5
-8x+8y=72
+ - -

The divergence theorem applies since

is a closed surface. We have

where

is the space enclosed by the surface

. The divergence of the given vector field is

So we can write the volume integral (in spherical coordinates) as
ANSWER B
16=22-6
