You cannot answer this with a normal shape. Any shape given would have less an infinite sides.
The exception to this would BE the shape with infinite sides and therefore by the same token, an infinite perimeter. So, the answer would be a "Fractal"
An octagon.
A circle has infinite sides. Otherwise it's a hecatommyriagon with 1000000 sides So yeah.
a shape with ten sides
Octagon.
There is no 'most' - if you had enough time, you could draw a polygon with a billion sides, or a billion billion...... Then you could still always add more sides.
the shape with the most sides is unknown
A 3d shape can have infinite sides
There is no such thing as the shape with the 'most' sides. No matter how many sides you draw a shape with, somebody else can easily come along and draw a shape with one or two or fifty more sides. The more sides a shape has, the more it gets to look like a circle.
octagon
There is no "most" with respect to polygons. You could make a shape with a million sides, and then make a new shape with a million and one, and keep going forever.
A circle as it has infinite number of sides
a sopidocihedron
A hexagon has six sides, while a pentagon has five sides, so a hexagon has the most sides.
How many sides does a circle have? Infinite So the answer is Infinite
An octagon.
It's like an oblong with weird sides.....It kind of has sides. most of them has
The Correct Answer is Irregular
