Answer:
The answer is 105.
Step-by-step explanation:
Answer:
It represents an infinite cylinder of radius 4.
Step-by-step explanation:
The first thing to notice is that

<u>represents a circle of radius 4</u>, with its center in the origin of a plane yz, of cartesians coordinates.
Starting from here, we have to put the coordinate x, for all values of x, to complete the space R³. <em>This will enlarge this circle we had on the plane, to infinity</em> (positive and negative on the x-axis).
Finally, we have that this region is a cylinder of radius 4, with center in y=0 and z=0, and of infinite length in the x coordinates.
