The circumference is the distance around a closed curve. It is used to mean the perimeter of a circle.The circumference is the distance around a closed curve (i.e. a circle).
Yes, a circle is a closed curve: its starting and ending points are the same. (any arbitrary point) Yes, it is a closed plane curve (two-dimensional line). A circle has a constant arc curvature, as compared to obloid or elliptical closed curves.

A [non-intersecting] closed curve
simple curve is a curve which doesnot cross itself,it neednot be closed....... but a simple closed curve is a curve which is simple and also closed. every simple closed curve is a simple curve but not vice versa.
A closed curve. This includes shapes made of straight-line segments.
The sir of astronomy said that space is curve but how that is possible according to me space can not curve if space is the form of curve than all galleries ,plants ,stars, and everything which belong to universe will be move in the same way but there are moving in special curve path . The curve path be may because of different forces which make them make is a curve path. The forces are well know my as . But on curve path I have a example suppose that you are moving on a path the path is curve you are moving in a straight line with any speed but it appear to as that we are moving in a curve path. in reality we are moving in straight line. same condition of earth which are moving in a curve due to same special forces not in a curve space. Now we know very wall that the curve path is due to same special forces which force any body to move in a curve path . In short the curve is due to same force , it is not mean that space is curve. If so than the shape of space is like Imagine the image
No, it is not.
helix
The answer depends on what you mean by shapes. These curves are not closed shapes.

A parabolic curve is a curve where any point in the curve is an equal distance from two areas. It is an equal distance away from the focus, or fixed point and the fixed straight line, or the directrix.
The graph if a function can be a curve, but it can also be any one of a ton of other shapes.
