It isn't possible to give a generalised formula for the circumference of an ellipse in terms of elementary functions.

The circumference (or perimeter) of an oval is represented by an infinite series based on multiple aspects of the oval including:

* Eccentricity

* Implied length ("major radius")

* Implied width ("minor radius")

Circumference is only used for circles. Perimeter is for every other 2D shape.


Can you make a sentence about circumference?

It seems quite strange that the circumference of the Moon, as observed from the Earth, matches the circumference of the Sun. The perimeter of a circle or of an ellipse is called the circumference.


What is the difference between an ellipse and an oval?

An ellipse always has two axes of reflection; an oval has one or more.So, an egg-shape is an oval, but not an ellipse.In short an ellipse is an oval, but an oval may or may not be an ellipse.


Is a circle an oval?

NO!!! Circle ; from its centre the distance to the edge(circumference) is equal . Ellipse(Oval) ;from its centre the distance to its edge(circumference) can vary. Casually, you can think of an oval as a squashed circle. In the coordianet plane ; A circle has the Equation x^2 + y^2 = 1 An Oval has the Equations x^2/a^2 + y^2/b^2 = 1 The 'a' & 'b' represent the eccentricity of the oval (ellipse), and the lengths of the major and minor axes.


What is the name of a shape with 2 straight and 2 curved sides?

It is simply an elongated circle, possibly an oval but NOT an ellipse. It is not an ellipse because it has two straight sections. An ellipse is curved at all points along its perimeter.


What is the true way to find the circumference of a oval?

Not quite sure what you mean by "true way". You can measure it with a string or a similar flexible object. Or you can measure length and width, and - assuming it is an ellipse - use the formula for the circumference of an ellipse - or rather, an approximation formula.

What do you call a stretched circle?

An oval. Or an ellipse.


What is the average circumference of a balloon?

A balloon is an oval so perimeter of an oval is: Perimeter = 2π√(a² + b²)/2 So for a balloon with 'a' being 25cm and 'b' being 15cm (kind of average) Perimeter = 2π 10.60660171779821
