<u>331.5 inches² </u><u>is the </u><u>area of the octagon</u><u>, rounded to the nearest square inch.</u>
What is octagonal in shape?
- In geometry, an octagon is a polygon that has 8 sides and 8 angles.
- All the sides are joined end to end to form the shape of the octagon.
- The sum of the interior angles of an octagon is equal to 180 degrees.
Solving for an area of a regular octagon, we can make use of the formula shown below:
Area = 1/2 × apothem × perimeter
In this problem, the following values were given such as:
Apothem = 10 inches
Perimeter = 66.3 inches
Put the values in the formula
Area = 1/2 × 10 × 66.3
Area = 331.5 inches²

Answer:
1 and 7/16, or 23/16
Step-by-step explanation:
Find the common denominator, which is 16.
_____ + 1/16 = 24/16
subtract 1/16
______ = 24/16 - 1/16
______ = 23/16
1+7/16 = 23/16
Answer:
The mean would be 6, meaning Tara is correct.
Step-by-step explanation:
The reason to why this is the answer is that I had to add all the “number of hours in a school per day” to get 30. Then, you would have to divide 30 by 5 (because you have five different hours for a school day) to get 6. Your mean would be 6 because mean is adding up the amount of something, then dividing it of how many numbers you added.
44 students in Mrs. Vitale's class read 11 books
<h3>Ratio and proportions</h3>
Let the number of students that read 11 books in Mrs. Vitale's class be x
If One fourth of the students in Mrs. Vitale's class read 11 books, then
1/4 x = 11 books
x = 11 * 4
x = 44
Hence 44 students in Mrs. Vitale's class read 11 books
