First of all, 'pi' is not a formula. It's a number.
Next, the number can never be written exactly correctly with digits, no matter how far
the decimal is carried out. That's why a symbol was invented to represent it.
'3.14' is a rough approximation for 'pi'. It's about 0.05% too small.
Many people use '22/7' for 'pi'. That's about 0.04% too big.
3.142 is better.
3.1416 is even better.
3.14159 is even better.
3.1415927 is even better.
3.1416592653589792 is even better.
'Pi' is just a characteristic of the thing we call a 'circle'. There's no 'why' pi is that
number. It's like asking why water feels runny, or why air doesn't smell.

If the area of a circle is 314 square inches what is the circumference of the circle?
62.8 inches. the formula for a circle's area is a = pi x r squared. substitute 3.14 for pi and 314 for a. 314 = 3.14 x r squared (divide both sides by 3.14) v 100 = r squared (find the square root of both sides) v r = positive or negative 10 . since it stands for the radius of a circle, it has to be positive. now that you know the circle's radius, you can solve the circumference formula, c = 2 x pi x r. c = 2 x 3.14 x 10 c = 62.8
