It is a cylinder.
No. Circles have absolutely no sides at all.
Circles
Cylinders are 3 dimensional shapes and they have a pair of parallel circles
If two circles are drawn using the same centre, the two lines of the circles are parallel as they don't meet each other.Two straight lines (think of railway tracks) are drawn next to each other, but never meet, they are parallel lines.
The circles could be in 2 planes that are parallel to each other. Lines and planes can be parallel. Lines of latitude are examples of circles that are in parallel planes.

The two circles at the top and bottom of the cylinder are parallel faces.
All parallels of latitude, except for the Equator, are not great circles. Great circles are the largest circles that can be drawn on a sphere and pass through its center, whereas small circles do not pass through the center of the sphere.
