Ellipsoid.

No.

an ellipsoid is the less formal name for a geoid which is a shape which is like a sphere but is bulgy round the middle

Newton was first claim that the earth is ellipsoid instead of spherical...

The joint between radius and scaphoid + lunate should fall into the category of an ellipsoid joint.

An ellipsoid.

No it is an oblate ellipsoid

your wrist is an ellipsoid joint

A semi-ellipsoid.

A paraboloid and an ellipsoid.

a sphere or an ellipsoid.

The term is ellipsoid (the special case, equal coordinate ellipsoid, is the sphere).

An ellipsoid with equal radii along two axes and a different radius in the third (a flattened sphere or a circular ellipsoid).

Ellipsoid joint

An ellipsoid.

Any spheroid or ellipsoid doesn't.

A sphere, an ellipsoid, a toroid and many more.

That is the correct spelling of "oval" (an ellipsoid shape).

An example of an ellipsoid joint is the wrist joint, which allows for a wide range of movement in multiple planes. This joint consists of the distal end of the radius bone articulating with the scaphoid and lunate bones of the wrist. The ellipsoid joint allows for flexion, extension, abduction, adduction, as well as circumduction movements.

More formally, an ellipsoid.

semi conjugate diameter of ellipse

A sphere or ellipsoid which has been sliced by a plane.

In 3 dimensions, a sphere, an ellipsoid, or a blob.

Yes.

A sphere, an ellipsoid, a toroid.

"Ovoid" is not clearly defined.

In the case of an ellipsoid, the figure is clearly defined, but - just as the circumference of an ellipse - the surface area of an ellipsoid is somewhat difficult to calculate, and can't be expressed in terms of elementary functions.

The Wikipedia article on "ellipsoid" has an approximate formula that you can use.

Both the Wikipedia and Wolfram Alpha have exact formulae; but understanding them requires some advanced math.

Ellipsoid joints are synovial joints found in the body that allow for movement in two planes. They consist of an oval-shaped convex surface that fits into a concave depression on another bone. This type of joint allows for flexion and extension movements, as well as some rotation and side-to-side movements.

Or an ellipsoid, or an irregular but smooth "lump".

Any ellipsoid, including the sphere.

The shape of the testes are ellipsoid in shape, meaning they are egg-shaped.

It can be a sphere, a spheroid, an ellipsoid, etc.

The geometric solid most similar to a lemon is an ellipsoid.

There are lots of shapes: a sphere, an ellipsoid, a smoothed blob.

A sphere, ellipsoid and an infinity of related shapes.

'If a, b, and c are the semi-axes, the volume is (4/3)πabc. When a b c the ellipsoid is a sphere and this formula becomes (4/3)πa3' (James and James, eds, Mathematics Dictionary D. Van Nostrand, 1960)
