Cone
it is a three dimensional cone , the circle is the edge of the figure and the curved side is the body of the cone, the vertex is the point of the cone
It is a cone.
A rectangular pyramid is a solid (3-dimensional) figure that comes to a point opposite the base (like the Pyramids of Egypt.) Its base is a four-sided plane figure with right angles and opposite sides equal (a rectangle--or square for that matter).
Oh, dude, a cone is neither acute nor obtuse because it's a three-dimensional object, not an angle. It's like asking if a banana is sweet or salty. But hey, if you want to talk about angles, the tip of a cone can form acute angles with its base, so I guess you could say it's a little edgy in that sense.

A spiraling or circular motion is characteristic of a transverse wave. This type of wave exhibits oscillations perpendicular to the direction of wave propagation. Examples include electromagnetic waves like light waves.
This is an impossibility. If it is a solid figure then it will have more than 1 surface. If it has only 1surface and it is a solid, then it must be a sphere, but the surface of a sphere is not flat is it? By using the word 'solid' then by definition, it is three dimensional and has thickness. A cylinder has no vertices , but it has 2flat surfaces. A vertex is a point where three lines meet, such as on a pyramid, which has 4 vertices. Have I forgotten something or is this a 'trick' question?

A Mirror?Answer:A perfect front surface mirror has an albedo of 100%; the polished surface of white metals like aluminum or silver comes close to that figure.
The concept of circular time comes from ancient Hebrew philosophy. It states that time is not linear, but circular, and unending. Therefore, a clock is circular, because time represents a continuous loop, that never ends.
Its a circular shaped bottom that comes to a point at the top.
A cone.

If you have one reference that leads to another and then another which finally comes back to the first, making a circle or closed loop, this is a circular reference.
