Do you know why there are 360 degrees in a circle?

様態の副詞

Is it just a random number that was chosen and could have easily bean 107 120 or anything else?

Or is there a more logical reason behind this?

There is no definitive answer to this question, but we do have a pretty good idea.

360 is a number that is divisible by every number from 1 to 10.

Apart from seven, it actually has a total of 24 numbers that it divides into.

This is a larger amount of devises than any other positive whole numbers up to its own value, which makes it a highly composite number.

For this reason, highly composite numbers are good base numbers to perform common calculations with, but this still seems a bit too random to justify.

Its is the number of degrees in a circle.

We know that there are roughly 365 days in a year.

But many ancient civilizations like the same Arians and Babylonian had 360 day calendars.

From their point of view, they were looking at the celestial sphere of stars that were of a fixed position in the sky.

Some would appear to move along in ecliptic path over the fixed stars for a duration of 360 days, moving one degree a day the same Arians and Babylonians also used the SEC Suggestible number system, which basically uses 60 is a base number when making calculations.

60 is a highly composite number, just like 360.

This makes it great for simplifying common calculations.

Using 60 is a base number you can half quarter and third it very easily half equals 30 a quarter equals 15 and 1/3 equals 20 Nice round numbers.

Now let's do it with 100 half equals 50 a quarter equals 25 but the third equals 33.3.

Recurring some arians and Babylonian is worked out.

That day to day calculations would be much easier using 60 rather than 100 or any other relatively low number if you took a circle and try to fit an equal actual triangle insiders using the circle's radius, you could fit a total of six within the circle.

Using the sex adjustable system, each would have a base value of 60 which multiplied by six is 360.

So in putting these factors together, we can say these are the most probable reasons why we have 360 degrees in a circle.

Do you think this all adds up or do you have any other theories?
