Challenge Problem: Determine the perimeter of the part to the nearest inch. Approach: Find the perimeter of the part with no cutouts, subtract the diameter of each cutout then add half the circumference of each cutout. Challenge Problem: Determine the area of the part to the nearest square inch. Challenge Problem: The diagram represents one section of a wrought iron fence. Determine the length of material needed for 27 sections like this. Round to the nearest in. Approach: Total the six straight lengths with the 5 arcs then multiply by 27. Find the weight of the table frame in the drawing to the nearest pound. (you will need the appendix to find the weight of the feet).
