Question

Explain how you know pi is a constant. Use ratios of two circles to justify your answer.

Answer 1

ratio is a constant since all circles are geometrically similar and linear proportions between any similar geometric figures are constant.

Explanation:

Answer 2

is defined to be the ratio of the circumference of a circle over its diameter (or 2 times its radius). This ratio is a constant since all circles are geometrically similar and linear proportions between any similar geometric figures are constant.
