Find the area of a regular hexagon if given a side length of 1.9 to the square root of 3.

dalvyx [7]

Answer:

28.137 sq. units.

Step-by-step explanation:

Area of a regular hexagon is

$A=\dfrac{3\sqrt{3}}{2}a^2$

where, a is the side length.

It is given that the side length of the regular hexagon is $1.9\sqrt{3}$ .

Substitute $a=1.9\sqrt{3}$ in the above formula.

$A=\dfrac{3\sqrt{3}}{2}(1.9\sqrt{3})^2$

$A=(1.5\sqrt{3})(10.83)$

$A=16.245\sqrt{3}$

$A=28.137$

Therefore, the area of regular hexagon is 28.137 sq. units.

Give an example of each of the following situations explain your choices

Harrizon [31]

1. When determining the average change in a data set
2. When the data is skewed. You'll need to relocate your central station of data. Because the skewed data is dragging all your data away from its true typical value.(If the data is correct then the answers of mean, median, and mode should almost be identical.)
3. Determining the most common category, typically based on data points or a graph (example: transport)

Hope this helps!! :)
