a circle can do neither, if you mean a sphere then I must inform you to remember that a circle is 2D and a sphere is 3D..... So spheres can't do either, they often get tired and goto sleep.
Because the sides are like a circle.
no

Yes
A circle cannot slide in the traditional sense because it is a two-dimensional shape without edges or points to grip a surface. However, if a circle is represented as a solid object, like a wheel, it can roll along a surface, which may be perceived as sliding in a broader context. The movement of a circle in a linear direction depends on its form and how it interacts with the surface beneath it.
