Answer: B is correct. Triangle PRS can be proven equilateral, and the hexagon is equilateral.

Step-by-step explanation: We can't see the theorem she applied however

From the construction, we can see that the arcs are drawn properly to construct an equilateral hexagon, and the component triangles are all equilateral

The circumference of Circle K is pi. The circumference of Circle L is 4xpi.

Answer:

Ratio of circumferences: $\displaystyle\frac{1}{4}$

Ratio of radii: $\displaystyle\frac{1}{4}$

Ratio of areas: $\displaystyle\frac{1}{16}$

Step-by-step explanation:

Hi there!

We are given:

- The circumference of Circle K is $\pi$

- The circumference of Circle L is $4\pi$

Therefore, the ratio of their circumferences would be:

$\displaystyle\frac{\pi}{4\pi}$ ⇒ $\displaystyle\frac{1}{4}$ when simplified

The formula for circumference is $C=2\pi r$ , where <em>r</em> is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.

If the circumference of Circle K is $\pi$ , or $1\pi$ , then its radius is $\displaystyle\frac{1}{2}$ .

If the circumference of Circle L is $4\pi$ , then its radius is $\displaystyle\frac{4}{2}$ , which is 2.

Therefore the ratio their radii would be:

$\displaystyle\frac{\frac{1}{2}}{{2}}$ ⇒ $\displaystyle\frac{1}{2}*\frac{1}{2}$ ⇒ $\displaystyle\frac{1}{4}$ when simplified

The formula for area is:

$A=\pi r^2$

First, let's find the area of Circle K:

$A=\pi (\displaystyle\frac{1}{2})^2\\\\A=\displaystyle\frac{1}{4}\pi$

Now, let's find the area of Circle L:

$A=\pi (2)^2\\A = 4\pi$

Therefore, the ratio of their areas would be:

$\displaystyle\frac{\frac{1}{4}\pi}{4\pi}$ ⇒ $\displaystyle\frac{\frac{1}{4}}{4}$ ⇒ $\displaystyle\frac{1}{4} * \frac{1}{4}$ ⇒ $\displaystyle\frac{1}{16}$ when simplified

I hope this helps!

Which of the expressions has a sum of 15.41? Select all that apply. A. 11 . 38 + 4 . 03 B. 10 + 5 . 41 C. 12 . 38 + 2 . 93 D. 9

marta [7]

Answer: A. 11 . 38 + 4 . 03

B. 10 + 5 . 41

D. 9 . 2 + 6 . 21

Step-by-step explanation:

Step 1

Compute the sum of the given options

a) 11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

c) 12 . 38 + 2 . 93= 15.31

d) 9 . 2 + 6 . 21 =15.41

e) 7 . 54 + 6 . 87=14.41

Step 2

Eliminate the expressions that do not give a sum of 15.41 , we have

a) 11 . 38 + 4 . 03 = 15.41

b) 10 + 5 . 41= 15.41

d) 9 . 2 + 6 . 21 =15.41

Therefore, the expressions with sum of 15.41 are A, B and D
