Answer:
C = 2√(Aπ).
Step-by-step explanation:
The area A = π r^2 where r = radius
and the circumference = 2 π r.
From the formula for the area r = √(A / π)
So the circumference is found by substituting in C = 2 π r for r:
C = 2 π √(A / π)
C = 2√(Aπ).

Answer:
-22 or -2
Step-by-step explanation:
<u>Understanding size</u>
If RS is 10, it does not matter where they are. As long as they are 10 units apart, it works.
However, we already know S lies at -12 so we only have 2 choices for R.
Check the picture I uploaded for better understanding.
This is because RS doesn't mean that R has to be before S. It just means that they are a segment. This means that RS and SR are the same segments.
