I was taught that "pi" is the ratio of the radius and/or diameter of a circle to its circumference.

What circle's circumference and diameter were measured to be able to get a number that has hundreds of numbers after the decimal point?

For many practical purposes, 22/7 (3-1/7) or 3.1416 seems to be a fairly close approximation.

lol...I remember 3.14 from school.

The decimal number is just a close approximation of the irrational fraction 22/7.

Pi is the ratio of the circumference of a circle to its diameter. Pi = C/D. Pi is always the same number. Pi = 3.14159 rounded..how about this..Sorry I love math!

I do believe that the ratio of the circumference to the diameter of ANY circle will be 'pi'. It's also the ratio of the area of the circle to the square of its area.

Are you celebrating National PI day next Monday (3/14)?

In my circles pi is spelled pie and it is usually sliced in about 6 to 8 pieces.


Sorry I couldn't resist :-P

Emerald and quilt1950 are correct...doesn't make any difference on the circumference...the ration of circum. to diameter is ALWAYS pi.

Whatever it is, isn't it obvious that only a man could come up with something neverending and repetitious? A woman wouldn't.

ROFL!! 6 to 8?!!? in my circles we are lucky to get 4! :XD:

Ditto!
