Circles, parabolas, ellipses,and hyperbolas are called conic sections because you can get those shapes by placing two cones - one on top of the other - with only the tip touching, and then you cut those cones by a plane. When you move that plane around you get different shapes.

What are the geometric characteristics of a circle ellipse parabola and hyperbola?
They are all conic sections.
Which shape have no straight edges?
There are infinitely many shapes. Amongst them are conic sections (circle, ellipse, parabola, hyperbola); epicycles, cardoids, etc; totally irregular shapes like blobs or outlines of clouds or puddles of water; etc.
What is the circumference of an ellipse?
It isn't possible to give a generalised formula for the circumference of an ellipse in terms of elementary functions.
What is the formula for finding the area of an ellipse?

What is the mathematical shape of an egg?
I think it's an ellipse. Ellipse is most likely the closest shape of an egg.
Which Conic sections describes a closed curve?
Circles, parabolas, ellipses, and hyperbolas are all conic sections. Out of these conic sections, the circle and ellipse are the ones which define a closed curve.
What are the different types of conic section and circles?
Conic sections are derived from the intersection of a plane and a double cone and include four main types: ellipses, parabolas, hyperbolas, and circles. A circle is a special case of an ellipse where the two foci coincide, resulting in a constant radius from a central point. Ellipses have two focal points, parabolas have one focus and a directrix, while hyperbolas consist of two separate branches defined by two foci. Each type has unique mathematical properties and applications in geometry and physics.
How are parabolas and ellipses related?
They are both considered as "conic sections". If you take a cone and slice it slightly slanted, you get an ellipse. In the case of parabolas, if you cut off a side (not the tip) vertically, you end up with a parabola.
Is every circle an ellipse?
Yes; the circle is a special case of an ellipse.
What is an eccentric circle?
For Ellipse: The 2 circles made using the the ellipse center as their center, and major and minor axis of the ellipse as the dia.For Hyperbola: 2 Circles with centers at the center of symmetry of the hyperbola and dia as the transverse and conjugate axes of the hyperbolaRead more: eccentric-circles
How are ellipses used in real life?
Parabolas are used in satalights and flash lights and archiceture and maths, whoever wrote eggs is very wrong parabolas ends never meet * * * * * All very true. The only problem is that a parabola is not an ellipse! One of the main uses for an ellipse is to describe planetary orbits.
What conic sections describes a closed curve?
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
Is all ellpses circles?
No. A circle is a special kind of ellipse.
What is the ellipse of an oval?
An ellipse is the locus of a point such that the sum of its distance from two fixed points is the same. The shape is like a stretched circle but its circumference does not become a straight line.An oval is an imprecise term for all kinds of "stretched" circles. The word is derived from ova = egg so an oval could have the shape of the cross section of an egg; it could be an ellipse or it could be like a running track, which consists of two semi-circles with parallel straight sections.
What is a ellipse drawing?
"Elliptical" means they look like ellipses.
What conic sections represent a closed curve?

Who replaced circles with ellipse in a heliocentric model of the universe?
