39. Find the circumference of a circle with radius of 18 in. Leave your answer in terms of pi 324pi In.
54pi in
36pi in.
18pi in.

36pi

Step-by-step explanation:

multiply the radius by 2 to get 36 but dont multiply by pi just put 16π

113pi in

Step-by-step explanation:

This should be the answer I checked my work a bunch of times either I'm wrong or something.

Because since we know the area is 18in we multiply that by 2 to get the diameter of 36,

then multiply that by pi.

There should be 113pi in somewhere in there.

:/ I dont know maybe I'm wrong I'll consult with others.

sine

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
