It can be formed by rotating an [[ellipse]] about its [[minor axis]], forming an equator with the end points of the [[major axis]]. As with all ellipsoids, it can also be described by the lengths of three mutually perpendicular principal axes, which are in this case two arbitrary equatorial [[semi-major axis|semi-major axes]] and one [[semi-minor axis]].
 
An everyday example of an oblate spheroid is the shape of confectionery such as [[Smarties]] or [[M&M's]]. The [[Figure of the Earth|shape of the Earth]] ([[geoid]]) is very close to that of an oblate spheroid. Though local [[topography]] deviates from this idealized [[spheroid]], on a global scale these [[Deviation (statistics)|deviation]]s are very small.

==Properties==
An oblate spheroid with ''b < a'' has [[surface area]]
 
:::<math>S_{\rm oblate} =  2\pi a^2\left(1+\frac{1-e^2}{e}\tanh^{-1}e\right)
\quad\mbox{where}\quad e^2=1-\frac{b^2}{a^2}</math>
 
and [[volume]]
:::<math>V_{\rm oblate} = \frac{4}{3}\pi a^2 b</math>.
 
The oblate spheroid  is generated  by rotation about the minor axis of an ellipse with semi-major axis ''a''  and semi-minor axis ''b'', therefore ''e'' may be identified as the [[eccentricity (mathematics)|eccentricity]] (see [[ellipse]]). A derivation of this result may be found at.<ref>http://mathworld.wolfram.com/OblateSpheroid.html</ref>
 
==Aspect ratio==
The [[aspect ratio]] of an oblate spheroid/ellipse, ''b'':''a'', is the ratio of the polar to equatorial lengths, while the '''[[flattening]]''' (also called '''oblateness''') ''f'', is the ratio of the equatorial-polar length difference to the equatorial length:
 
: <math>f=\frac{a-b}{a}=1 - b:a.</math>
 
These are just two of several different parameters used to define an ellipse and its solid body counterparts.
 
The oblate spheroid is the approximate shape of many [[planet]]s and [[Astronomical object|celestial bodies]], including [[Saturn]] and [[Altair]];
in particular, cartographic and geodetic systems for the [[Earth]] are based on a [[reference ellipsoid]].

Over use of enemas and laxative, drinking alcohol leads to this problem. If you have these symptoms, and they don't improve when treated naturally, you may need to speak to a doctor to make sure they're not more serious. As long as we stick to these hemorrhoid treatment tips, then we will get along with our lives just fine. Warm sitz baths and using a cold compress will also help reduce the pain. Apply Ice - The coolness of the ice delivers immediate relief to the hemorrhoids.

However, if you're attempting to find a pro camera, let me stop you at this time and tell you to look somewhere else as this doubtless won't be anywhere near your expectancies. The search for effective hemorrhoid treatments can be time-consuming for those who suffer from hemorrhoids, but there are options, including the all-natural Clear - Med oral supplement guaranteed for 60 days and helps shrink, heal and soothe hemorrhoids. By simply controlling your diet, exercising daily, etc. Hemorrhoids are a common medical condition, that can be extremely painful and uncomfortable. Fiber supplements can help some people, but cause gas, bloating, and constipation in others.

It is very helpful to people who are working or managing a business company. They prefer to utilize stimulants, eat strong foods, and drink alcohol. Typically after the actual surgical procedure, the recuperation period is often 4 to 6 weeks. That excessive reliance on quickly-meals may be the primary motive of this ailment, a illness present mainly within the abundant countries. Resources for the above information: Revolution - Health.

Pregnancy and abnormally high tension of the internal sphincter muscle can also cause hemorrhoidal problems, presumably by means of the same mechanism. The foods that your child eats play important role in treating hemorrhoids. One of which is to radically increase fiber and water intake. Finding natural cures for hemorrhoids that work well is really unpleasant because you may have to experience the ineffectiveness of many products in the process. About Holly Hayden; Holly is an independent researcher and columnist residing in Northern California.

Stop Hemorrhoids Fast With a Proven Natural Treatment Millions of people have discovered this unique treatment and are surprised by the results. It is always advisable to rectify this disorder at the earliest possible stage to prevent serious complications in the future. The first advice medical experts give to pile sufferers is not to feel bad about themselves, lots of other people including doctors have the same ailment.
