What is the area of the sector a.) 10π cm^2b.) 16π cm^2c.) 40π cm^2d.) 64π cm^2

Natalija [7]

Answer:

C. 40π cm²

Explanation:

• The central angle of the sector = 225 degrees

• The radius of the sector = 8cm

For a sector of radius r and central angle θ, we calculate the area using the formula below:

$\text{Area}=\frac{\theta}{360\degree}\times\pi r^2$

Substituting the given values, we have:

$\begin{gathered} \text{Area}=\frac{225}{360}\times\pi\times8^2 \\ =\frac{5}{8}\times64\times\pi \\ =5\times8\times\pi \\ =40\pi cm^2 \end{gathered}$

The area of the sector is 40π cm².

how do you have a reflection in the x axis, if the shape is already partially in the third and second quadrent of the graph

IgorLugansk [536]

Its a reflection over an x-axis, whats "positive" goes "negative" and whats "negative" goes "positive" with respect to y.

If a shape $S$ is a subset (made of $P_2\cup P_3$ of quadrants $Q_2,Q_3$ then the part $P_2$ that lies in the second quadrant gets mapped to $Q_3$ and part $P_3$ that lies in third quadrant gets mapped to $Q_2$

Hope this helps.

Find the value of 5.8 divided by 1.2

Katena32 [7]

It is easier to do if we get rid of the decimals, so lets multiply both numbers by 10:
5.8/1.2 = 58/12
and reduce the fraction:
= 29/6
then operate:
= 4.83
