Volume d'une calotte ellipsoidale |
2002-12-11 |
|
Fabien pose la question :
Quel est le volume d'une calotte d'ellipsoide de hauteur h (ellipse de longueurs d'axes a, b, et c)? Je souhaite une formule exacte, un développement limité, voire une intégrale à estimer numériquement. Quelle méthode pour le calculer ?

The volume of half an ellipsoid |
2012-08-10 |
|
Darcy pose la question :
Hi,
I need to calculate the volume of half an ellipsoid, split horizontally along the long axis. In effect, an oval shaped mound of soil. So the bottom would be an ellipse. I have the length, width and height measurements but not the formula. Thanks!

The volume of an ellipsoid |
2010-01-01 |
|
Barbara pose la question :
I need to calculate the volume of an ellipsoid with the dimensions:
102.5 mm x 57 mm x 57 mm = L x W x H
I am using the formula V = 4/3 pi (.5L)(.5W)(.5H), but it isn't giving me a reasonable
number.

What shape do I say a football is? |
2005-11-14 |
|
Peter pose la question :
I am a 43 year old man. I am no longer in school, I have a bachelors degree. I like to tell stories about sports in ways to make people think about the amount of time they devote to the sports. For example, while attending a church in Chicago on the north side, I would pass by Wrigley field.
I began to call it the church of the flying orb or sphere. Now if I want to tell a similar story about football (not soccer), what shape do I say a football is?

A decreasing ellipsoid |
1999-12-15 |
|
A student instructor pose la question :
The volume of an ellipsoid whose semiaxes are of the lengths a,b,and c is 4/3 *pi*abc. Suppose semiaxes a is changing at a rate of A cm/s , the semiaxes b is changing at B cm/s and the semiaxes c is changing at C cm/s . If the volume of the ellipsoid is decreasing when a=b=c what can you say about A,B,C? Justify.

Volume of an ellipsoid |

Michael Nowicki pose la question :
I am a physician at the University of Mississippi. I am trying to compare the size of polyps (abnormal growth of tissue in the colon) between 2 groups of individuals. The department of pathology gives the size as length X width X depth - how do I calculate the volume? Polyps are nearly ovoid in shape.
