How many yards do you need for a 132 Round Tablecloth?

There are two solutions.

First, just cut your round tablecloth out of a length of fabric, and throw away the waste corners.

Second, make a number of triangles (6 to 10), long thin wedges each one sixth (tenth) of the circumference at the sort end, and the length of the wedge being the radius of your table. sew them together to make your circular tablecloth out of the wedges, and trim off the surplus.

And all possible answers will need you to assume a particular width for the cloth.
