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!
