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>
The formula for the area of a circle is pi*r^2. 3.14*16^2 = 803.84 centimeters squared
The answer is a because if you divide 1000 by 2 you get 500 and the other ones you get a decimal.
So 10 questions is 100% you missed 30% of the questions so you would do 100%-30% which is 70%
