Cylinder? That's only if the sides are perfectly straight. If it bulges in the middle, like a barrel, I don't know.
There is no name but a cylinder is the nearest standard geometric shape.
I believe it is Rhombus
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
A 5-sided 2-dimensional figure is a pentagon and a 5-sided 3-dimensional shape is a pentahedron.
A cube...
Well, honey, the geometric name for the shape of a carrot is a "cylindrical tapered" shape. So next time you're munching on a carrot, just remember you're chomping on a fancy geometric figure. Keep on snacking, darling!
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
sphere
A heptagon.
There is no name but a cylinder is the nearest standard geometric shape.
A solid shape.
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 two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
I believe it is Rhombus
