The simplest answer is to look at it this way. Take a circular piece of steel (not a flat disk but a rod formed into a circle). The center of mass will be in the center of the circle, which is not within the body of the steel.
No, the center of mass of a body cannot lie where there is no mass. The center of mass is a point that represents the average position of all the mass in a system. In the absence of mass, there is no center of mass.
No, the center of gravity of a solid body may not always lie within the body. It depends on the distribution of mass within the body. If the mass is distributed symmetrically, then the center of gravity will be located within the body. However, if the mass distribution is asymmetrical, the center of gravity may lie outside of the body.

The center of gravity always lies within an object, and is the location at which the entire mass can be considered acting at a single point.For a system of more than one object, the center of gravity can lie anywhere between the farthest points of the objects, depending on the distribution of mass. The center of mass is called the barycenter.
The center of mass of a solid object may or may not lie within the object. For example, in a uniform sphere, the center of mass lies within the object at the geometric center. However, in objects with irregular shapes or voids, the center of mass may lie outside the physical boundaries of the object.
Yes. For example, the center of mass of a hollow sphere would be at the empty center of that sphere.

Center of mass is the point where the entire mass of body can be concentrated. As the force applied on a body passes through its center of mass then the body gets displaced other wise that will be rotated about the axis passing through its center of mass.
Yes, the center of mass could potentially be located inside a hole within a body if the distribution of mass is such that the center of mass ends up there. The concept of center of mass is a point where the body's total mass can be considered to be concentrated, regardless of its physical shape.
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
No, it may lie outside the body. In case of a circular ring, it is at the centre of the ring which is outside the mass of the ring.
No, the center of mass of a solid object does not necessarily have to lie within the object. For example, a hollow sphere or a ring has its center of mass located outside of its physical structure. This is because the distribution of mass in these objects is not uniform.
