Step-by-step explanation:

You don't really find the Sin of things yourself. You usually use a calculator and It is mostly used for finding measurements of other angles, and sides of a right triangle. I suggest using WolframAlpha or the app Calculator on your phone to calculate such things.

Answer:

Dilation factor is 2/3

Step-by-step explanation:

Look at both flat lines (M to S and M' to S') and find their lengths.

M to S = 9 units

M' to S' = 6 units

The triangle has gotten smaller so the dilation factor is a fraction

new/original = 6/9 = .66666666 or 2/3

Dilation factor is 2/3

The diagram shows a sector of a circle radius 10cm. Find the perimeter of the sector, giving your answer correct to 1 decimal pl

qwelly [4]

<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Anyway, I'll help you either way. A sector is a region of a circle between two radii. Let's assume the sector as:

$s=25\pi cm^2$

Then, we can find the central angle by the following equation:

$s=\frac{\theta}{360}\times\pi r^{2} \\ \\ r=10cm \\ \\ s=25\pi cm^2 \\ \\ \\ So: \\ \\ \frac{25\pi(360)}{10^2\pi}=\theta \\ \\ \theta = 90^{\circ}$

But:

$90^{\circ}=\frac{\pi}{2}$

Then:

$C:Perimeter \ of \ sector \\ \\ \\ C=\theta r \\ \\ C=\frac{\pi}{2}(10) \\ \\ C=5\pi cm \approx \boxed{15.7cm}$
