Answer:
the answer is B
Step-by-step explanation:
First you find 10% of 50 which is 5 and then to find 20% you just double that amount, 20%= $10.
The amount of material needed for the containers is its surface area
The amount of material needed for the 8 containers using the assumed parameters is 3080 square feet
<h3>How to determine the amount of material?</h3>
The question is incomplete, as the figure of the right pentagonal prism is not given.
So, I will provide a general explanation.
The surface area (SA) of a right pentagonal prism is:
SA = 5b(a + h)
Where:
- b represents the base length
- a represents the apothem
- h represents the height
From the question, we have the height of the prism to be 8 ft.
Assume that:
a = 3 ft and b = 7 ft
The equation becomes
SA = 5 * 7 * (3 + 8)
Evaluate the product
SA = 385
The amount of material needed for the 8 containers would be:
Amount = 8 * 385 square feet
Amount = 3080 square feet
Hence, the amount of material needed for the 8 containers using the assumed parameters is 3080 square feet

Answer:
6. 113.1
8. 63.62
Step-by-step explanation:
6. Circle area = π * r² = π * 36 [inch²] ≈ 113.1 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 6 [inch] * 2 = 12 [inch]
8. Circle area = π * r² = π * 20.25 [inch²] ≈ 63.62 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 4.5 [inch] * 2 = 9 [inch]
