Answer

The given equation represents a circle in a 2D system and it represents a cylinder in a 3D system.

1Step 1. Part (a) of the question.

The given equation is: 

$${x}^2 + {y}^2 = 4 $$

 


The above equation represents a circle with its center at (0,0) in a two-dimensional system.


2Step 2. Part (b) of the question

The given equation   $$x^2+y^2 =4 $$  represents a cylinder in a three-dimensional system.
