is there any formula to measure the area of oval object?

Answer 1

If you mean an ellipse shape then the area is Pi * a * b where a and b are the semimajor and semiminor axis. See

http://en.wikipedia.org/wiki/Ellipse#Area

Answer 2

Yeah, that's a pretty tough one.

I guess one has to think of an oval as being egg-shaped for this to be tough, yet satisfyingly solvable. If it is pictured as close enough to an ellipse, then find the area of said ellipse and multiply by a factor one uses to estimate how much similarity it has to the ellipse. The 0.8 one person suggested seems reasonable. But if you think of it as being egg-shaped:

then personally, I would treat the fat end of the oval like half an ellipse (calculate the area for the full ellipse, then take half of it) and the top half as a parabola (pick a height on the Y axis as a stopping point so the ellipse and the parabola contribute half each to the height of the oval) and adjust its generating formula to shape it so the oval looks "right" and then calculate the area to that chosen Y value (with its vertex at Y=0 for simplicity). Then add the two "half areas" together for a total area. (Similarly for the volume of an "egg.")

Answer 3

Well, yes and no. Calculating the area of an oval (or "ellipse") is actually one of the more complicated calculations you can make in planar geometry, because essentially there are so many more variables than initially met the eye. To get an accurate area, you should probably use calculus, but to get a rough number for a simple ellipse (a circle stretched along a single axis), you can use the following;

A = pi a b

where a and b are the semiaxes (the "radii" in each direction.) It's
just the familiar "pi r squared" with each "r" replaced by one of the axes.

A = pi a^2 * b/a = pi a b

Answer 4

Assuming oval means ellipse, area of oval is Pi * a * b, where a is half of length(major axis) and b is half of width(minor axis).

Circle is oval where a = b = r(radius) and area is pi * r * r,

Answer 5

The area of an ellipse is Pi*a*b, where a and b are the semi major and semi minor axes of the ellipse. Similarly going a step further the volume of an ellipsoid is Pi*a*b*c

Answer 6

an oval object would be a circumference and the area of a circumference is (2 * 3.14 * R) with R being the radius of the circumference (oval)

Answer 7

Width x Length x 0.8
