Ornamental and decorative molding in ancient Greek architecture was different depending on which order of architecture it came from. There are three classic Greek orders that progress from fairly simple to quite ornate: Doric, Ionic, and Corinthian.
A barrel vault is a simple roof with a curved, semi-circular cross section, used to span large distances, such as found in railway stations and churches.
It depends on the shape. Many prismatic or conical shapes have simple cross section - such as a polygon, a circle or an ellipse. These have simple, though different, formulae.

Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse
The simple answer is that an ellipse is a squashed circle.A more precise answer is that an ellipse is the locus (a collection) of points such that the sum of their distances from two fixed points (called foci) remains a constant. A circle is the locus of points that are all the same distance from a fixed point. If the two foci are moved closer together, the ellipse becomes more and more like a circle and finally, when they coincide, the ellipse becomes a circle. So, a circle is a special case of an ellipse.

The circumference of an ellipse is given by an integral, though it can be approximated through some workable formulae. One such formula gives an approximate length of 72.66 ft (if the lengths given are diameters; if they are semi-axes, it gives a length of approx 145.33 ft - twice as long as the ellipse is twice as big).
The orbit is elliptical, and in simple cases, the centre of the two bodies' mass is at one of the foci of the ellipse.

The ancient Greeks used Ptolemy's theory, based on circles, that was good enough for the accuracy needed at the time. Later Kepler in the 16th century discovered that an ellipse is a better model of a planetary orbit. In modern times it has been discovered that an ellipse is an approximation and that true orbits have no simple description. But the ellipse is a good enough model for many purposes.
