<u>Given</u>:
The given figure is a square pyramid.
The side length of the base of the pyramid is 6.6 feet.
The height of the pyramid is 12.672 feet.
We need to determine the volume of the pyramid.
<u>Area of the base:</u>
The area of the base can be determined using the formula,

where a is the side length of the base.
Substituting a = 6.6, we get;


Thus, the area of the base is 43.56 square feet.
<u>Volume of the pyramid:</u>
The volume of the pyramid can be determined using the formula,

where A is the area of the base and h is the height of the pyramid.
Substituting A = 43.56 and h = 12.672, we get;


Thus, the volume of the pyramid is 184 cubic feet.
Answer:
p = 26.3
Step-by-step explanation:
Using the law of sines
sin 101 sin 38
--------- = ------------
42 p
Using cross products
p sin 101 = 42 sin 38
p = 42 sin 38 / sin 101
p=26.34175
To the nearest tenth
p = 26.3
The problem ask to find the value of the cos(infinity) and the best answer, base on my further calculation and formulation that came up to a solution that leads me to an answer that the cos(infinity) is undefined but it has a range of (-1,1). I hope you are satisfied with my answer and feel free to ask for more
