The Mathematics of Flat Circles

Explain the relationship between Pi, stitch height, and the number of increases needed per round to create a flat circle.

Determine the ideal number of segments (repeats) for a design based on the stitches used in the first round.

Calculate the specific increase formula required to maintain a flat circle for single, half-double, and double crochet stitches.

Identify the visual signs of "ruffling" (too many increases) and "cupping" (too few increases) and relate them to the underlying math.
