Given:
Side length of base = 8
Slant height = 6
To find:
The surface area of the square pyramid.
Solution:
Surface area:

where A is the area of base
p is the perimeter of base
s is the slant height
Area of base (A) = 8 × 8
= 64
Perimeter of base(P) = 4 × 8
= 32
Substitute these in the formula:



The surface area of the square pyramid is 160 unit².
200 - 118 = 82
82/200 = 0.41
0.41 x 100 = 41%
Answer: False
Step-by-step explanation:
False, the value of cosine at pi and 2pi is equal to -1 and 1 respectively. You can test this by using the pi circle or a calculator. Let pi = 180 degrees. Cosine is always defined and alternates between 1 and -1.

Answer:
120 sq ft.
Step-by-step explanation:
REMEMBER: Area is found by multiplying one side, by the other side that isn't the same length as it.
Multiply 12 by 10 to get 120
120 is the area of the bedroom
