Define a CIRCLE does it have a begining and an end?

Question

Dont hurt your brains too much

Answer 1

A circle is a collection of a series of point, each one of which is exactly the same distance away from the centre. A circle does not have a beginning or and end.

Answer 2

Definition: A circle is composed of all points on a plane equidistant from a single point (a sphere is the same figure, but in 3 dimensions; hypersphere is the same in 4 dimensions, appx). I wouldn't say it has a "beginning or end" per se. Though commonly, in math, we tend to start the unit circle from (0,1) and draw it counter clockwise until it gets back to (0,1). But a fully drawn circle doesn't have an explicit beginning or ending. It is continuous. If any part of the circle was NOT drawn, it would by definition be an arc, but not a circle, since circle implies completeness. Whereas an arc generally has a specific beginning and ending point.

Answer 3

A circle is the collection of all points in a plane that are the the same distance from a fixed point in that plane, the fixed point being the center.

Unlike a line segment, it has no beginning or end.

Answer 4

No, place a circle on the ground "already made in circular way" it wo't have a beginning or end.

Answer 5

Yes. The moment the circle comes into existance it began, and the moment it no longer exists, it ends.

Answer 6

Definition:

(x-h)^2+(y-k)^2=r^2 where (h,k) is center of circle

Well you assume that the beginning and the ending point is the same 0degrees=360degrees

Answer 7

It has an area = pi r^2

Answer 8

no but it has a middle and its fat
