The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.The answer will depend on what measure is required: length of a side, perimeter, radius or diameter (if circular), eccentricity (if an ellipse), area.
The ellipse will become more circular until it becomes a circle when the two foci coincide.
Assuming a circular cylinder:Cutting lengthwise, you get a rectangle.Cutting parallel to the circular bases, you get a circle. Cutting at an angle, you can get an ellipse - or a shape that has parts of an ellipse, as well as straight lines.

Earth's orbit (revolution) around the Sun is not circular - it's an ellipse. However, this ellipse is fairly close to a circle.

A sphere is three-dimensional whereas an ellipse is two-dimensional. An ellipse can have an oval shape but a cross section of a sphere is always circular.
The ellipse will become more circular until it becomes a circle when the two foci coincide.
An ellipse with less eccentricity will be closer in shape to a circle, so it will generally be smaller than an ellipse with more eccentricity which is more elongated. The size comparison also depends on the specific dimensions of the ellipses.

In a right circular cone the base is a circle and the sloped side is a sector of a circle. For a general cone, they are an ellipse and a sector of an ellipse.
No, the earth's motion is a periodic motion forming an ellipse.
As with all the planets, the orbit of Neptune is a nearly circular ellipse.
The orbits of planets are actually elliptical, not perfectly circular. An ellipse is a stretched-out circle. The shape of a planet's orbit can be described as an ellipse with the Sun at one of the two foci.
Most orbits are elliptical; all NATURAL orbits are. There are two foci, or focuses, to an ellipse. The distance between the foci determines how eccentric, or non-circular, they are. If the two foci are in the same place, then the ellipse becomes a circle. So a circular orbit would have only one focus.
No, the orbits of planets are not perfectly circular but are elliptical in shape. The path of planets around the Sun can be best described using Kepler's laws of planetary motion, which state that planets move in elliptical paths with the Sun at one of the foci of the ellipse.
