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
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.
If the circumference of Circle K is , or 
, then its radius is 
.
If the circumference of Circle L is , then its radius is 
, which is 2.
Therefore the ratio their radii would be:
⇒ 
⇒ when simplified
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
I hope this helps!
The amount of paper that are needed to line the bottom of 3 drawers with paper is equal to 2,160 square inches.
<h3>How to determine the amount of paper?</h3>
First of all, we would calculate the area of the bottom of each drawer as follows:
Area = length × width
Area = 36 × 20
Area = 720 square inches.
Next, we would multiply this area by 3:
Total area = 720 × 3
Total area = 2,160 square inches.
