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.
A cylinder.

Half a sphere, which is a 3D shape, is called a hemisphere. The semi-circles in the question is a 2D shape and will make a circle.
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
Circles have a completely curved shape, and NO sides. So do ovals.
a cylinder has two faces that are circles
No, ovals and circles are different shapes. Ovals have an elongated, slightly oblong shape with two different radii, while circles have a round shape with a single radius.
