Home Economics Class
For a project in the Home Economics Class, Kirk is making a tablecloth for a circular table 3 feet in diameter. The finished tablecloth needs to hang down 5 inches of the edge of the table, the whole way round. Kirk will fold under and sew down 1 inch of material all around the edge. Kirk is going to use a single piece of rectangular fabric that is 60 inches wide. What is the shortest length of fabric, in inches, Kirk could use to make the tablecloth without putting any separate pieces of fabric together?

Convert the diameter of the table in inches so 3 feet is 36 inches. Now we know that the tablecloth needs to hang 5 + 1 inches of the table (1 because Kirk folds under and sew 1 inch of fabric) so our full length of the tablecloth, in any straight line, will be: 1 + 5 + 36 + 5 + 1 = 48 inches.
