# Quick Answer: Where Does A Circle Start And End?

## Who invented circle?

The greeks considered the Egyptians as the inventors of geometry.

The scribe Ahmes, the author of the Rhind papyrus, gives a rule for determining the area of a circle which corresponds to π = 256 /81 or approximately 3.

16.

The first theorems relating to circles are attributed to Thales around 650 BC..

## Can a human draw a perfect circle?

Mathematically speaking, there is no such thing as a perfect circle. That, however, hardly matters with drawing—in most cases, you just need to be close enough to be believable. The fact is, you can get pretty darn close with a certain amount of practice. … You can not draw a circle, you can only draw a picture of one.

## Who found pi?

Archimedes of SyracuseThe Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

## Is Infinity a circle?

The circle is the symbol for infinity, because the circle is endless, and may be considered a polygon with an infinite number of sides.

## What is circle and its types?

A circle is the set of all points at a specific distance from a given point in two dimensions. concentric circles. Two or more circles that have the same center, but different radii. congruent circles. Two or more circles with the same radius, but different centers.

## Who is the god of math?

ThothHis name is Thoth. He’s the ancient Egyptian god credited with inventing mathematics.

## Who found zero?

MayansThe first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.

## Can a circle have a radius of 0?

If a point can be a circle, then nothing stops the point from being any regular shape. … A circle with a radius of 0 is just a point.

## Is a great circle infinite?

A great circle is the largest circle that can be drawn on any given sphere. … The exception is a pair of antipodal points, for which there are infinitely many great circles. The minor arc of a great circle between two points is the shortest surface-path between them.

## Where does a circle end?

greg1313. A circle is the set of all points that are of equal distance from a point with that distance being greater than zero — no “beginning” and no “end”.

## Why is a circle infinite?

A circle is basically an infinitely sided regular polygon. Otto Isaacs, Only infinity makes any sense. Assuming you mean by circle the circumference of a circle, then yes, you may say it is infinite, meaning that that specific curve has no beginning and no end.

## Are perfect circles possible?

No, it is not possible to make a perfect circle. At it’s most fundamental level, the universe has a minimum length of space called the ‘Planck Length’. Any and all circles that exist in nature therefore do not have infinite sides, but a number of sides equal to their circumference split into planck lengths.

## Do circles have infinite corners?

It might be more defensible to say that a circle has infinitely many corners than infinitely many sides (although this is not a question that seems to get asked very often). To start with, if a corner of a square is a point at which its boundary line is not straight, then every point on the circle satisfies that.

## What is Circle of Safety?

In his book, Leaders Eat Last, Simon Sinek explains the concept of a Circle of Safety: “Only when we feel we are in a ‘Circle of Safety’ will we pull together as a unified team, better able to survive and thrive regardless of the conditions outside.” If the circle is broken, group strength diminishes.

## Is Circle the perfect shape?

Because of its symmetry the circle is considered as the perfect shape. It is the symbol for the total symmetry of the divine (sic!).

## How many ends does a circle have?

two endsA circle does not have any sides as it’s made up of arcs, creating a continuous line that meets at two ends. All parts of a circle are of equal…

## What is the circle concept?

‘Circles Concept’ assists the student to group people within colour-coded circles of interaction. This allows the student to learn appropriate behaviours that could be used with people within each coloured circle.

## Does a circle have 0 or 1 side?

Two: the inside and the outside. A circle has zero sides. A side is a line segment.

## Is a circle a one sided shape?

Although a circle is a shape, it is not a polygon, so it does not have sides. If that isn’t convincing, consider process of elimination – it can’t have one side, because by definition sides are (straight) line segments.

## Is the Circle Software real?

Is The Circle A Real App? The Circle starts with eight players in an apartment building, but they won’t meet each other face to face unless they make it to the final. Instead, they communicate strictly through The Circle app. Unfortunately, The Circle isn’t a real app.

## Is the sun a perfect circle?

The sun is the most perfectly round natural object known in the universe, say scientists who have conducted precise measurements of its dimensions. As a spinning ball of gas, astronomers had always expected our nearest star to bulge slightly at its equator, making it very slightly flying-saucer shaped.
