The 'symbol' is a letter in the Greek alphabet - which is pronounced 'pi'. The connection between the letter and the ratio of the diameter and the circumference fo a circle may come from the fact that the letter pi is the first letter of the Greek word for perimeter, and the word for periphery.
The symbol for pi (π), is the Greek letter that is the equivalent to the Roman p. It is the Greek letter pi. It is the first letter of the Greek word περίμετρος (perimetros) from which our word perimeter comes.
The symbol of pi is 16th letter of the Greek alphabet and it was chosen because the first letter of the equivalent of the word perimeter begins with pi in the Greek language.
The ancient Greeks did the original work of inventing geometry as we know it, and pi is a letter in the Greek alphabet, so it was a convenient symbol for them to use.
A chemical symbol refers to a chemical element; the first letter of a symbol depends on the chemical element.

'CO' is NOT an equation, but a chemical formula. 'CO' is Carbon Monoxide. NB Do not confuse with 'Co' , which is the chemical symbol for cobalt.

For a two letter chemical symbol, the first letter is always a capital letter and the second letter is always small/lower case, e.g. 'Fe' Iron.
