never tried it without my Gay lines so I wouldn't know for sure, but try 3 and see what you get
If it is a regular nonagon then it has 9 equal sides, so all you needed to do was divide 31.23 by 9. (You would have got 3.47 cm)
12 of then but if they are joined together in the form of a 6 sided hexagon then 6 endpoints are needed.

You would need basically a protractor and a straight edge.

Minimally, two (2) trapezoids are necessary to create a hexagon. (This solution comes from drawing a line straight across the center of the hexagon.) Most numbers (if not all) greater than two are also feasible, but with more finagling.

A square triangle and hexagon are alike becaue they are shapes. they are also alike because the have straight lines and no curved. each of the shapes have a base and at least 2 corners. hope these are good for what you needed and sorry if not.
Add extra zeros if needed to the dividend 3.2 Pretend there is no decimal and divide. Bring the decimal straight up.
5 straight lines are needed to construct a pentagon.
