My mom wanted to buy fabric to cover our semicircle window, and she wanted to know how many feet of the fabric to buy, and how much adhesive she needed in order to put it up. In order to find the area, I used ½(3.14)(30^2), which ended up to be 1413.71 in, or about 118 ft. Consequently, I told my mom to buy around 150 ft of fabric, in order to have enough. Next, I found half of the circle's circumference, plus the diameter, which ended up in resulting in 154.25 in, or about 12.85 feet.
