Carol is going to paint a wooden archway in her backyard that is built on a concrete pad. The wooden archway consists of four posts, which are each 6-by-6 inches and 7 feet tall, and a curved roof (that is shaped like a hollow half cylinder). The outer diameter of the roof is 6 ft and its inner diameter is 5.5 ft. The arch is 6 ft long. Carol knows that she will need about 1 gallon of paint to paint every 350 square feet (with only one coat). She also knows that 1 gallon of paint weighs about 11.5 lb. If she plans on using two coats of paint, how much weight will she add to the structure? Round the answer the nearest tenth of a pound.
