How to find the Curcumfrence and diameter of an oval?

Answer 1

the oval shape has two diameters
the circumference =pi*(d1+d2)/2
where d1 and d2 are the diameters

Answer 2

By an oval, I think you mean an ellipse, which is an elongated circle. Circumference of an ellipse uses a famous calculus integral to find it. The more convenient way is to approximate using algebra: C ~ 2pi*sqrt(a^2+b^2)/2
A and B are the different radii of the oval (long and short).
By diameter I assume you mean the longer radius. Wherever the oval's circle is "stretched," you measure that and it's the diameter.

Answer 3

Circumference Of An Oval

Answer 4

I'm going to assume that the type of oval you refer to is an ellipse (since if it is something similar to egg-shaped, finding the area gets really complex).

An ellipse has a horizontal diameter (which we'll denote a) and vertical diameter (which we'll denote b). There isn't one diameter.

The circumference of an ellipse is not a simple one as the circumference of a circle; it involves summations and series.

The area of an ellipse, however, is simply
A = (pi)ab

Answer 5

There is a specific form of oval, the ellipse,
which has specific graphical formula,
"diameters" (major and minor axes), and specific
circumference.

As you know, an "oval" is simply an egg-shaped figure.

To find the circumference of an oval, you may cut it out
of cardboard and roll it edgewise on paper to find the
circumference.

What do you mean by "Oval"? An ellipse?

Answer 7

Average over all the way round.

Answer 8

more better if you use the square root, more accurate than the pi*(d1+d2)/2..i suggest
