A Norman window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 51.4 ft. give the area A of the window in square feet when the width is 9.9 ft. Give the answer to two decimal places.
9.9 + 1/2 (9.9)pi +2 h = 51.4
h = 12.97 ft (of the rectangular area)
Area = 9.9 * 12.97 + 1/2 (9.9/2)^2 pi = 166.93 ft2
9.9 + 1/2 (9.9)pi +2 h = 51.4
h = 12.97 ft (of the rectangular area)
Area = 9.9 * 12.97 + 1/2 (9.9/2)^2 pi = 166.93 ft2
