Web(2001-10-23) What is the surface area of an ellipsoid? [spheroid] There are simple formulas for the surface area of an ellipsoid of revolution, but when the 3 semiaxes (a, b, c) are distinct, the formula isn't elementary:. The surface area of an ellipsoid of equation (x/a) 2 +(y/b) 2 +(z/c) 2 =1 is: where. The above was originally posted here to provide a correct … The equation of a tri-axial ellipsoid centred at the origin with semi-axes a, b and c aligned along the coordinate axes is $${\displaystyle {\frac {x^{2}}{a^{2}}}+{\frac {y^{2}}{b^{2}}}+{\frac {z^{2}}{c^{2}}}=1.}$$ The equation of a spheroid with z as the symmetry axis is given by setting a = b: $${\displaystyle {\frac … See more A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. … See more The most common shapes for the density distribution of protons and neutrons in an atomic nucleus are spherical, prolate, and oblate spheroidal, where the polar axis is assumed to be the … See more • Media related to Spheroids at Wikimedia Commons • "Spheroid" .

WebIf any two of the three axes of an ellipsoid are equal, the figure becomes a spheroid (ellipsoid of revolution). There are two kinds of spheroid: oblate spheroid (lens like) and prolate spheroid (сigar like). Volume of spheroid is calculated by the following formula: Unlike ellipsoids, exact surface area formulas exist for spheroids: WebThe red oblate spheroid (flattened sphere) corresponds to μ = 1, whereas the blue half-hyperboloid corresponds to ν = 45°.
