SUMMARY
The perimeter of an oval, specifically an ellipse, can be approximated using the formula p = 2π√((a² + b²)/2), where a and b are the semi-major and semi-minor axes, respectively. However, there is no simple exact formula for the perimeter of an ellipse; evaluating it requires understanding elliptic integrals. For precise calculations, numerical methods are recommended. The discussion emphasizes the importance of clarifying the definition of "oval" to ensure accurate mathematical communication.
PREREQUISITES- Understanding of basic geometry, specifically ellipses
- Familiarity with the concept of semi-major and semi-minor axes
- Knowledge of elliptic integrals and their applications
- Basic numerical methods for approximating mathematical functions
- Research the properties and equations of ellipses
- Learn about elliptic integrals and their significance in mathematics
- Explore numerical methods for calculating the perimeter of complex shapes
- Investigate online resources for geometric formulas and their derivations
Mathematicians, geometry enthusiasts, students studying advanced mathematics, and anyone involved in computational geometry or numerical analysis.

Approximately
p =2 \pi \sqrt { \frac {a^2 + b^2} 2}}
Where a and b are the "radius" .
If you want exact you will need to be able to evaluate an elliptic integral... You up for that?

What, exactly, do Y0U mean by "oval". I might be inclined to assume a quadratic formula, but it seems clear that you do do not p[/b}] \pmean tnat

Do you mean an ellipse? This is a specific type of an "oval" and is like a streched out circle. It follows the formula:
\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1
Unfortunately, there is not a simple exact formula for the perimeter of an ellipse. You might want to check out this website for more information: http://home.att.net/~numericana/answer/ellipse.htm#elliptic

Until you can say what you mean by "oval" I'm afraid this makes no sense at all.

Here's a webpage that has a few area formulas, including the formula for an ellipse: http://www.math.com/tables/geometry/areas.htm
Hope that helps.

I have made a call on this thread. I will assume that by "oval" means ellipse. Further, this is not a homework question. Until the OP checks back in there is not really much more to be said.
The formula I provided is for the perimeter of an ellipse. The precise method, which may well be in fact the basis for the name Elliptic Intergral, is beyond fundamental math and may be best done numerially. Thus it may provide the basis for a broader dissussion of an interesting topic.
