Answer: It will be needed 864 square feet of glass to cover the Skywalk floor.
Step-by-step explanation: The figure below shows the area in question.
Area of a circle is given by

The walkway is a semicircle. Then, area will be:

The area that will be covered with glass is the area between the outer and the inner circles. So, area is

Answer:
-18+9k
Step-by-step explanation:
If you use the distributive property, you get:
(-3*6) and (-3*-3k)
If you simplify each of them you get:
-18+9k

Answer:  25</h3>
Through using the pythagorean theorem, you should find the hypotenuse of the smaller triangle to be 10 units. Therefore, the perimeter of the smaller triangle is 6+8+10 = 24 units.
The perimeter of the larger triangle is 60 units. The ratio here is 24:60 = 2:5
Meaning that the larger perimeter is 5/2 = 2.5 times that of the smaller.
We apply this scale factor 2.5 to the smaller hypotenuse 10 to jump to 2.5*10 = 25, which is the length of the larger hypotenuse.
