Okay, so the picture is given clearly, everything is in there, you know, and we're writing an integral dz dy dx, right? so we need to identify the boundaries of z, y, and x.
00:17
Z is, from the picture, it's super clear, right? you see that from paraboloid to this plane, the yellow plane? so i'm going to say z is x squared plus y squared, 2, 2, 4, y.
00:35
Okay? now for the x and y boundary, we need to look at this, you know, projection in the xy plane.
00:45
Projection in the xy plane is a circle, okay? let me use this space over here.
00:55
It's a circle, and i can draw it this way so you can see it.
01:02
And i'm going to stick with the same layout here.
01:07
This is y, and this is x.
01:10
This is 2, this is 4.
01:12
So the top part is y is positive, which is 4 minus x squared, because radius is 2...
