An ellipse is a 2-dimensional figure and so the formula isVolume = 0.
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
An ellipse is 2-dimensional; it has no volume. The area of an ellipse is pi * A * B, where A and B are the lengths of its axes.
The formula for an ellipse is (x/a)2 + (y/b)2 = c2 where a and b are the lengths of the semi-axes and c is a constant.
It isn't possible to give a generalised formula for the circumference of an ellipse in terms of elementary functions.
You know the formula for the area of a circle of radius R. It is Pi*R2. But what about the formula for the area of an ellipse of semi-major axis of length A and semi-minor axis of length B? (These semi-major axes are half the lengths of, respectively, the largest and smallest diameters of the ellipse--- see Figure 1.) For example, the following is a standard equation for such an ellipse centered at the origin: (x2/A2) + (y2/B2) = 1. The area of such an ellipse is Area = Pi * A * B , a very natural generalization of the formula for a circle!
No because the formula for finding the area of an oval, which is an ellipse, is quite different
If R is the horizontal radius and S is the vertical radius, the Cartesian formula for an ellipse is:f(x) = plusminus (S/R)(sqrt(R2-x2))
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.
It is pi*a*b where a and b are the lengths of the semi-major and semi-minor axes.
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
