Answer:
C = 8 pi cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
16 pi = pi r^2
Divide each side by pi
16 = r^2
Taking the square root
4 = r
The circumference is
C = 2 * pi *r
C = 2* pi *(4)
C = 8 pi cm
It’s not a function because when it’s graphed put it doesn’t pass the vertical line test
I have no idea what you're talking about. Can you explain in detail plz?
Are you solving for X? If so, your answer will be x=-3. Hope this helps!
