Another cylinder if you dissect it horizontally. In other cases, the name is unknown.
Another cylinder
Dome
If you cut a rectangle in half you wouldn't get a solid figure at all, since a rectangle is a plane figure. If you made a straight line cut you would get either a triangle or a quadrilateral of some variety depending on exactly how the cut was made.
A rectangular prism or a cuboid.
you cut it into regular solids then figure out those then add them together

A conical frustum, tat is, a cone with its apex cut off. It is usually NOT a cylinder because it gets narrower as you get higher.

If the cylinder is cut in half along the side it is still a cylinder. If the cylinder is cut in half along one of the circular faces it is a horizontal cylindrical segment, which would look like a pig trough not hollowed out.
If you were to cut a cube in half along any plane passing through its center, you would get two equal halves of a cube. Each half would still have the shape of a cube with the same dimensions, just split into two separate pieces. The resulting solid figures would be two smaller cubes.
a circle
A cross section of a cylinder along its length is called a rectangle. When a cylinder is cut along its length, the resulting shape is a rectangle with a length equal to the circumference of the cylinder and a height equal to the height of the cylinder. The area of this rectangle represents the lateral surface area of the cylinder.
That's not even a question. Are you describing a cylinder?Cylinders have a circular base (the part on the "top" and "bottom") and then a tube-like figure between the two bases.
