Answer:
24 inches
Explanation:
First, we need to convert the height of the wall to inches since the diameter of the window is given in inches:
18 feet = 18 x 12 inches = 216 inches
Next, we can find the distance from the floor to the top of the window by subtracting the height of the door from the height of the wall and then dividing by 2 (since the window will be centered above the door):
Distance from floor to top of window = (216 inches - 80 inches) / 2 = 68 inches
Finally, we can use the Pythagorean theorem to find the distance from the ceiling to the top of the window. We can consider the triangle formed by the height of the wall, the distance from the floor to the top of the door, and the distance from the floor to the top of the window. We can let x be the distance from the floor to the top of the window, then we have:
x^2 + 80^2 = 216^2
Simplifying this equation, we get:
x² = 216² - 80²
x² = 43,296 - 6,400
x² = 36,896
x =
= 192 inches
Therefore, the distance from the ceiling to the top of the window is:
Distance from ceiling to top of window = 216 inches - 192 inches = 24 inches
So the distance from the ceiling to the top of the window is 24 inches.
