An eleven sided shape is called a hendecagon.
a shape with eleven sides is called a undecagon
Hendecagon
A shape w/ 11 sides is called a hendecagon.
hendecagon ( dot know spelling)
An 11 sided polygon is an undecagon
An eleven sided polygon (2D shape with straight sides) is called a Hendecagon.I often set this as a research puzzle for my mathematics classes!
A polygon having eleven sides can be called a hendecagon or an undecagon. It can also be called an 11-gon.
A two-dimensional eleven-sided figure is called a hendecagon.
A cubic metre is a measure of volume: it does not, in any way, specify the shape. So the shape could be a parallelepiped with sides, a nonagonal prism with eleven sides, a cylinder with three or simple a blob!
A hendecagon, also known as an undecagon, is a polygon with eleven sides and eleven angles. Therefore, it has eleven faces if considered in a three-dimensional context, such as in polyhedra. However, when referring to a two-dimensional shape, it is typically said to have one face, which is the flat surface enclosed by its sides.
