If pie is round then does that mean its also pi(3.14)

no because if your talking about like pumpkin pie or apple pie the the pie or pie tin has a circumference when pi 3.14 is an ongoing number.

Pie is completely unrelated to the math term of pi, so whether it is round or not is irrelevant.

If the term pi is asked to be rounded however, you would in theory use 3.14 for the rounded version of π (3.141592653589793238462643383279502884197169399375105)

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
