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




864
<u>To cover the Skywalk floor is needed </u><u>864</u>
<u> of glass</u><u>.</u>
Step-by-step explanation:
The radius <em>r</em> is 5 in (r = D/2). so the volume <em>V</em><em> </em>of the beach ball is


Trigonometry is the branch of mathematics that studies the relationship between the sides lengths and angles in a triangle.
<h3>What is trigonometry?</h3>
Your information is incomplete as the triangles aren't given. Therefore, an overview will be given.
It should be noted that trigonometry simply means the branch of mathematics that is concerned with angles and their application to calculation.
In this case, studies the relationship between the sides lengths and angles in a triangle. The there basic functions in trigonometry are sine, cosine, ad tangent.

Step-by-step explanation:
SSS
SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. For example: is congruent to: (See Solving SSS Triangles to find out more) If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent
SAS
The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
ASA
ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. For example: is congruent to: (See Solving ASA Triangles to find out more)
AAS
The Angle Angle Side postulate (often abbreviated as AAS) states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.
Answer:
f(- 6) = 70
Step-by-step explanation:
To evaluate f(- 6) , substitute x = - 6 into f(x)
f(- 6) = 2(- 6)² - 2 = 2(36) - 2 = 72 - 2 = 70
