A 4 dimensional object is called a Tesseract or "hybercube"
Although if you want to get into string-theory and related advanced subject matters, the Tesseract is not a 4 dimensional object at all, but simply an advanced 3 dimensional object which only represents the 4th dimension; a visual aide if you will.
A polygon is a 2-dimensional shape whereas a hexahedron is 3-dimensional. Therefore a polygon that is a hexahedron could by called a geometric impossibility.
The name of an eleven sided geometric shape is a Hendecagon or endecagon.
Its the name for a shape
A solid shape.
A heptagon.
The geometric name for the shape of a carrot is a "cylindrical cone." This shape is formed by a combination of a cylinder (the body of the carrot) and a cone (the tapered end). In geometric terms, a cone is a three-dimensional shape with a circular base that tapers to a point, while a cylinder is a three-dimensional shape with two parallel circular bases.

Cylinder? That's only if the sides are perfectly straight. If it bulges in the middle, like a barrel, I don't know.
sphere
A solid shape.
A heptagon.
There is no name but a cylinder is the nearest standard geometric shape.
A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
A three-dimensional octagon is commonly referred to as an "octagonal prism." This geometric shape consists of two parallel octagonal bases connected by rectangular faces. The octagonal prism retains the properties of an octagon while extending into the third dimension.
I believe it is Rhombus
