What are ellipsoids?
A surface whose plane sections are all either ellipses or circles. A football approaches being an ellipsoid as does a discus.
What is a 3-D object whose bases are circles and lateral face is a rectangle?
Cylinder
What are at least 2 objects whose outlines are like an ellipse?
2 objects are a race track and an egg. I know this because it was part of my science homework.
What are the quadrilaterals whose diagonals cross at right angles?
They are either kites or (if the diagonals bisect each other) rhombuses.
What is an example of a quadrilateral whose diagonals are congruent but do not bisect each other?
I think this is impossible the diagonals of a four sided figure will cross
What are ellipsoids?

Is a solid whose bases are congruent circles?
cylinder
What is the outline of a cross section of earth?
Any way you slice the earth, you get a chunk whose outline is a circle. (or approximately a circle if you look closely the mountains and valleys that the cross section cuts through disturb the circle). a mathematical sphere will give a mathematical circle at all cross sections.
What do the circles in venn diagrams represent?
Each circle defines the boundaries of a set, all of whose members share a characteristic. All objects with the characteristic are inside the circle, all those without that characteristic are outside.
What are small circles according to algebra and trigonometry?
They are circles whose radii are smaller than some value set by the user.
What objects float and what objects don't?
Objects whose density is lower than the density of the fluid they're in float. Objects whose density is higher than the density of the fluid they're in don't.
What is a 3-D object whose bases are circles and lateral face is a rectangle?
Cylinder
What objects that sink in water?
the objects whose density is more than that of fluid sink in the liquid
What is circular cylinderical coordinates system?
Usually, cylindrical coordinates refers to the transformation x = r cos(theta), y = r sin(theta), z = z, although x, y, and z can be permuted. Cylindrical coordinates (r, theta, z) are very useful for describing three-dimensional objects whose cross-sections are easy to express in polar coordinates. Circular cylinders are a good example.
Which are objects whose noums begin with q?
Quail, quarter, quill and quilt are objects. They begin with the letter q.
What is the fraction of 720 degrees?
The answer depends on the number whose fraction you are trying to find.
Which things float on water and which sinks into it?
Objects whose aggregate density is less than the density of water float in it. Objects whose aggregate density is greater than the density of water sink in it.
