Yes if cut in half from its apex to its base diameter.
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.
hemisphere
Cut a sphere in half which is called a Hemisphere and you have 2 sides. The cut side and the sphere side.
Depends on the way you cut the cone, but the outline is either an ellipse or a parabola.
it a cone cut in half from the top
It is called a frustum.

To cut something in half is called "halving." This involves dividing an object or quantity into two equal parts.
hemisphere
A truncated cone is basically a cone with it's tip cut off.
There is no frustum of a cone. There is a frustum, which is a cone with the top cut off parallel to the ground.
You simply calculate it like a cone, but the height of the cone is the height to the top of the FILLED part, not all the way. Half-filled is not enough information . . . there can be "half filled" meaning half the height of the cone, but can also be "half filled" meaning half the volume of the cone.
Whats a diagram
It becomes an hemisphere
It is called symmetry. When an object is cut in half and both sides are identical, it exhibits symmetry.
