How many square feet of glass are needed to cover the skywalk floor? (round your final answer to 1 decimal place and any intermediate calculations to 2 decimal places. Be sure to include units. ).

Respuesta :

The area of the skywalk floor is the amount of space it occupies

The area of the skywalk floor is 1728.1 square feet

From the complete question, we have the following parameters

The outer diameter is 65 feet

This is represented as: [tex]\mathbf{d_2 = 65}[/tex]

The inner diameter is calculated as follows:

[tex]\mathbf{d_1 = 65 - 2 * 10}[/tex]

[tex]\mathbf{d_1 = 45}[/tex]

So, the area of the skywalk floor is the difference between the areas of the two semicircles.

This is represented as:

[tex]\mathbf{Area = \frac{\pi d_2^2}{4} - \frac{\pi d_1^2}{4}}[/tex]

Rewrite as:

[tex]\mathbf{Area = \frac{\pi}{4}(d_2^2 - d_1^2)}[/tex]

So, we have:

[tex]\mathbf{Area = \frac{3.142}{4}(65^2 - 45^2)}[/tex]

[tex]\mathbf{Area = \frac{3.142}{4}(2200)}[/tex]

Simplify

[tex]\mathbf{Area = 3.142 \times 550}[/tex]

[tex]\mathbf{Area = 1728.1}[/tex]

Hence, the area of the skywalk floor is 1728.1 square feet
