For a project in 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 over the edge of the tablecloth, Kirk will fold under and sew down 1 inch of the material all around the edge. Kirk is going to use a single piece of rectangular fabric that is 60 in wide. What is the shortest length in fabric, in inches, Kirk could use to make the tablecloth without putting any separate pieces of fabric together?
Answer= 48.
Explanation= Before doing anything else, you need to convert your measurements into the same scale. We are working mainly on inches, convert the table with 3 foot diameter into a table with (3)(12)=(36) inch diameter. Now we know the tablecloth must hang an additional 5+1 in on every side, so our full length of the tablecloth in a straight line will be:
1+5+36+5+1=48 inches
