Answers
Answer:
108inches^2
Step-by-step explanation
.............................................
Divide the hexagon in identical triangles.
Triangle area = length × width / 2
6 × 6 = 36
36/2= 18
The area of a regular hexagon is 85.28 square inches.
Given that, Lin and Andre used different methods to find the area of a regular hexagon with 6-inch sides.
We need to find the area of a hexagon using both methods.
What is the area of a regular hexagon?The formula for the area of a regular hexagon is (3√3 s²)/2, where 's' is the length of the side of the hexagon. Since we are talking about a regular hexagon, it should be noted that all sides are of equal length. When one side of the regular hexagon is known, the area can be calculated with the formula, Area of the hexagon = (3√3 s²)/2, where 's' is the length of the side of the hexagon.
We know that, the area of an equilateral triangle=√3/2 × a².
So, the area of an equilateral triangle= √3/2 × 6²
=18√3 square inches
Now, the area of a hexagon=6×18√3
=108√3=187.06 square inches
Area of the rectangle = length × width = 10.4 × 6 = 62.4 square inches
Area of a triangle= 1/2 × Base × Height = 1/2 × 10.4 × 2.2 = 11.44 square inches
Now, 11.44 × 2=22.88
Area of a regular hexagon = 62.4+22.88 =85.28 square inches
Therefore, the area of a regular hexagon is 85.28 square inches.

Answers
Answer:
314
Step-by-step explanation:
20 in diameter means 10 in radius
to find area you do r^2(pi)
10x10x3.14
When solving for pie you want the radius to square it
This is the equation to look for;
R^2*pie!
That means 10 is our radius square it and get 100 then multiply it by 3.14 and you get 314!

Malik jogs twice every day in a 7-day week with his friend. In the afternoon, they jog 3/5 as far as they do in the morning. At the end of one week they have jogged a total of 20 4/25 miles. How far do Malik and his friend jog in the afternoon?
Answers
Answer:
1.08 miles
Step-by-step explanation:
Given: They jog a total of 20 4/25 miles in a week.
Therefore they jog (20 4/25)/7 = 2.88 miles a day.
If x is how many miles they jog in the morning, they jog 3/5x miles in the afternoon. So 1.6x = 2.88. Divide 1.6 on both sides to get x = 1.8.
1.8 * 3/5 = 1.08 miles

3. A woman put $580 into a savings account for one year. The rate of interest on the account was 6½%. How much was the interest for the year in dollars and cents?
4. A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly?
5. There are 28 students in a class. Sixteen of those students are men. What percent of the class are women?
Answers
Answer:
1 multiply 12,800 x 15 = 192,000 then divide 192,000 by 100 = 1,920 so the answer is $ 1,920
2 He paid $7200 for the wrecked car which is about 65% of the original price.
3Hence, interest over a year is $ 37.7 or 3770 cents.
4 The student answered 16 problems correctly on a math test that had 20 problems.
5 Total students in the class = 28
Number of students that are men = 16
Number of student that are women = 28 - 16 = 12
percentage of women in the class = 12 / 28 × 100
percentage of women in the class = 1200 / 28
percentage of women in the class = 42.8571428571
percentage of women in the class ≈ 42.9 %
