The Lee family wants to buy a new round dining table. Their rectangular door frame is 3 feet wide and 6.5 feet high. If the legs are attached to the table, approximate the greatest length of its diameter so that the table can be placed into the dining room.

Answer 1

There's a lot of possible data missing, but if the statement about having the legs attached is supposed to mean that the table must be carried straight through the door, legs first, then the diameter cannot be greater than the width of the door: 3 feet.
