Answer:20π
Step-by-step explanation:
equation of the circle
(x+3)² + (y-5)² = r²
now, (-9, -3) lies on it
So, (-9+3)² + (-3-5)² =r²
36+ 64 = r² =100
hence, r =10
So, circumference = 2πr = 20π
The correct answer is 11944444

Answer:
-15, no roots
Step-by-step explanation:
b^2-4ac to find the discriminant
1^2-4*2*2=
1-16=
-15
-15<0
so there are no roots
Answer:

Step-by-step explanation:
We can simplify this equation down until we have x isolated.

If we add 17 to both sides:

Now we can divide both sides by 3:

So
.
