The circumference of a circle is 18.84 inches. What is the circle's diameter?

6

Step-by-step explanation:

The circles diameter is 6 because circumference is found when you do pi x diameter and since 18.84 ÷ 3.14 = 6 that means our diameter is 6

Hope this helps!

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
