Answer:
Maximum width of image that can be viewed clearly on the cylindrical screen is 10 ft
Step-by-step explanation:
Here we have
Circumference of screen = 2πr = 120 ft
Angle that can be viewed horizontally either side of focus = 15°
Total angle view = 30°
Size of image that can be viewed = Object within 30° of focus
Maximum width of image that can be viewed clearly = Perimeter of 30° arc section of cylinder
Maximum width of image that can be viewed clearly = 30/360×120 ft = 10 ft.
Maximum width of image that can be viewed clearly on the cylindrical screen = 10 ft.
