Answer: 1809.56
Step-by-step explanation: Find The Radius Of A Quarter (Half Of The Diameter) Then Square The Radius, Or Multiply It By Itself. Then, Multiply The Squared Radius By Pi, Or 3.14, To Get The Area.
36/96 in simplest form is 3/8
Find angleK:
Angle k = 180-45-85 = 50
Both triangles have an angle equal to 85 and 45, which makes the 3rd angle in both triangles equal to 50
Because all three angles are the same the triangles are similar.
The best approximation to the number of seedlings that are at least 2 inches high in the <u>entire lawn</u> is:
<h3><em>Total</em><em>
Seedlings Calculation</em><em>.</em></h3>
To identify the total number of seedling in the entire lawn, first you must add all the seedling counted by the researchers:
- Counted seedlings = 82 + 87 + 95 + 99 + 102 + 106 + 111 + 115
- <u>Counted seedlings = 697</u>
Now, you must divide 697 in the number of regions taken by the researchers ( in this case were 8), this to obtain the average:
- Average seedlings by region =

- <u>Average seedlings by region = 87.125</u>
Now, how we know, the entire lawn has a length of 8 feet and a width of 8 feet, it means 64 regions of one feet by one feet, by this reason, we multiply the average of seedlings by the whole regions in the lawn:
- Number of seedlings in the lawn = 87.125 * 64
- <u>Number of seedlings in the lawn = 5576</u>
Taking into account the average of seedlings is 5576, the best approximates of seedlings that are at least 2 inches high in the entire lawn is <u>6400</u>.
