Mathematical is an ellipse
An ellipse.
it is shaped roughly like a bell... a bell curve.
When the moon is shaped like a ball it is called a full moon.
It is a ring like object. The ring of a circus for example. Your definition would be a closed plane curve, consisting of all points from a given distance from a point within it, called the centre
A tangent is an object, like a line, which touches a curve. The tangent only touches the curve at one point. That point is called the point of tangency. The tangent does not intersect (pass through) the curve.
That shape is called an 'oval' or an 'ellipse'.
An ellipse.
Yes it could.An ellipse is a specific shape with a mathematical formula and certain qualities (like the distance from one focus to the edge of the ellipse to the other focus is constant).An oval is not so precisely defined but is a closed curve.
