Sorry But there is no shape for me to look at to give you the answer :( Edit the question or just send me a screen shot of it in discord, mine is Mousycritter#2842
Step-by-step explanation:
This is the answer y= -x+3
The awnser is A because you just divid it
The intersection of the two surfaces occurs along the cylinder

, so we have the

- and

-coordinates of the points in the bounded region contained within

and

, while

.
The triple integral is then given by

where

denotes the bounded region in the first quadrant.
Integrating in Cartesian coordinates is easy enough to do in this order.
