To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m
Answer:
48 Yards long
Step-by-step explanation: You multiply 24x 2
The slope of the best fit for the 3 given points is 500, so the correct option is b.
<h3>
How to find the slope?</h3>
Remember that for a line that passes through two points (x₁, y₁) and (x₂, y₂) the slope is:
![s = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
With the 3 given points we can find 3 slopes, and then we will need to find the average of these 3.
The 3 points are: (3, 2,750), (6, 4,200), and (9,5,750)
Then the 3 slopes are:
![s_1 = \frac{4,200 - 2,750}{6 - 3} = 483.3\\\\s_2 = \frac{5,750 - 2,750}{9 - 3} = 500\\\\s_3 = \frac{5,750 - 4,200}{9 - 6} = 516.7](https://tex.z-dn.net/?f=s_1%20%3D%20%5Cfrac%7B4%2C200%20-%202%2C750%7D%7B6%20-%203%7D%20%3D%20483.3%5C%5C%5C%5Cs_2%20%3D%20%20%5Cfrac%7B5%2C750%20-%202%2C750%7D%7B9%20-%203%7D%20%3D%20500%5C%5C%5C%5Cs_3%20%3D%20%20%5Cfrac%7B5%2C750%20-%204%2C200%7D%7B9%20-%206%7D%20%3D%20516.7)
The average slope is:
![S = (483.3 + 500 + 516.7)/3 = 500](https://tex.z-dn.net/?f=S%20%3D%20%28483.3%20%2B%20500%20%2B%20516.7%29%2F3%20%3D%20500)
So the correct option is b.

4 1/2 + 3 1/4 + 2 1/4 = 10 pounds of apples.
10 pounds is approximately 4.5 kilograms.
The answer is 50 because you divide the mph with the hours
