Help with parametrization of surface

So this is the surface

Circular cylinder baud The portion of the cylinder (x - 2)^2 + z^2 = 4
between the planes y = 0 and y = 3

Using cylindrical coordinates

Using cylindrical coordinates you can get r the radius and set θ the angle with the x-axis (on the x-z plane) and the height y as parameters, where r=4^1/2=2.

You can write:
y=y,
x=2cosθ+2,
z=2sinθ

where 0<θ<2π and 0<y<3.
