Hexagon. Although circles would represent a more accurate omnidirectional coverage, when we want to group circles together, they overlap one another. Hexagon doesn't and still has a somewhat 'circular' shape.
A rectangle and two circles.
The shape that would go in the section where two circles overlap is known as a lens shape or a vesica piscis. This area represents the intersection of the two circles, where both circles share common points. The overlapping region can also be described as a curved shape that has two rounded edges, defined by the arcs of the intersecting circles.

A cylinder.
It means that all of the sides in the shape are the same shape and the same size and they slot together when you place the shapes together. * * * * * No, they do not slot together - as a lock and key would. Each one could exactly cover the other.

A rectangle and two circles.
As the foci of an ellipse move closer together, the ellipse becomes more circular in shape. When the foci coincide, the shape is a circle. Note that circles are a subset of ellipses.
There is no shape which has only circular faces.

Circles are the easiest shape to make.

Circles have a completely curved shape, and NO sides. So do ovals.
