Answer:
<u>The correct answer is that the area of the regular octagon is 309 cm²</u>
Step-by-step explanation:
There are several formulas for calculating the area of a regular octagon. We will use this one for solving this question because it does not require additional information .
Area = (2 * s²)/tan 22,5°
s = 8 cm
Replacing with the real values, we have:
Area = (2 * 8²)/tan 22,5°
Area = 2 * 64/0.4142
Area = 128/0.4142
<u>Area = 309 cm² (Rounding to the nearest tenth)</u>

Answer:
the fourth answer, hope this can help
1ft=12 inchs
15*12= 180inches
6*12 = 72 inches
1 *12 = 12 inches
Volume = 155,520
One brick = 48
155520/48 = 3240= total bricks needed
ANSWER= 3240
