10 people comfortably, but you can fit up to 12 people if needed. Any less than 9 people at a 72" table is too much room.
Somewhere around ten people.
A table which is 90 inch around its outside (circumference) is 28.648 inches (to 3 dp) across (diameter).
Table linen size will depend on the drop you need. For a 5 foot diameter (60 inch) ROUND table and using a 90 inch ROUND tablecloth your drop would be 15 inches all around the table. For a 5 foot diameter (60 inch) SQUARE table and using a 85 inch SQUARE tablecloth your drop would be 12 and a half inches all around.
Ten people can sit around a 48 inch by 96 inch table.
If the table is 60 inches across, the diameter is 60 inches.
8 people comfortably. You can sit up to 10 if needed but less than 7 is too much room.
The diameter of a 72-inch round table is 72 inches, as the term "diameter" refers to the distance across the table through its center. This means that if you measure from one edge of the table to the opposite edge, it will be 72 inches.
I think you will find that 60 refers to a 60 inch diameter (5 feet)

The surface of a circle is given by the formula d2pi/4, so for our 44 inch diameter table, that gives 484pi square inches, which is aproximately 1520.531 square inches.
You should be able to fit 4 people comfortably around a 60 inch round table. You could fit 6 people but they will be close to one another.
It is its radius which is 72/2 = 36 inches
