Answer:

<h2>B, θ=137,51°</h2>

Step-by-step explanation:

\alpha =\frac{l}{r}

alpha are the angle in radian.

l= lenght of de arc=12cm

r=radius=5cm

\alpha =\frac{12}{5} \\\\

Converting the radian angle to degrees:

α--->θ

π--->180°

θ=(180°*α)/π

using the fact that: α=12/5

θ=(180°*12)/5

θ=432°/π

θ=137,5098°

θ=137,51°

The sum of all interior angles in a polygon is
180(n - 2), where n = the number of sides in the polygon.

now, notice this figure above, it has 5 sides, namely is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or 540, therefore

\bf (4x)~+~(3x+15)~~+~~(4x-25)~~+~~(3x+25)~~+~~(2x-3)=540&#10;\\\\\\&#10;16x+12=540\implies 16x=528\implies x=\cfrac{528}{16}\implies x=33

Pls help It’s due tomorrow question is in the picture
Slav-nsk [51]

Answer:

C

Step-by-step explanation:

Let's find the area of each of the two circles.

First Circle:

The first circle has a diameter of 10 inches. That means the radius is 5 inches. So, its area is:

A=\pi r^2\\A=\pi (5)^2\\A=25\pi

Second Circle:

The second circle has a diameter twice that of the first. So, the diameter is 20 inches. This means that the radius is 10 inches. Find the area:

A=\pi r^2\\A=\pi (10)^2\\A=100\pi

Now, find the ratio between them by dividing:

\frac{\text{Smaller}}{\text{Larger}}=\frac{25\pi}{100\pi}

Simplify:

\frac{\text{Smaller}}{\text{Larger}}=\frac{1}{4}

1/4 is the same as 1:4

So, our answer is C      :)
