Answer:
Ratio of circumferences: 
Ratio of radii: 
Ratio of areas: 
Step-by-step explanation:
Hi there!
We are given:
- The circumference of Circle K is 
- The circumference of Circle L is 
Therefore, the ratio of their circumferences would be:
 ⇒
 ⇒  when simplified
 when simplified
The formula for circumference is  , where <em>r</em> is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.
, 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  , or
, or  , then its radius is
, then its radius is  .
.
If the circumference of Circle L is  , then its radius is
, then its radius is  , which is 2.
, which is 2. 
Therefore the ratio their radii would be:
 ⇒
 ⇒  ⇒

The formula for area is:

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

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

Therefore, the ratio of their areas would be:
 ⇒
 ⇒  ⇒
 ⇒  ⇒
 ⇒  when simplified

<h3>Answer:</h3>
For your first answer it is because they are two different ways to solve the equation
<h3>Step-by-step explanation:</h3>
For Example!
<h2>Solution 1:</h2>
(x-4)² – 28 = 8The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)
<h2>Solution 2:</h2>
(x-4)² – 28 = -8
The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!

Answer:
87.92
Step-by-step explanation:
3.14(a² + ab)
= 3.14 (4² + 4 × 3)
= 3.14 (16 + 12)
= 3.14 × 28
= 87.92
