Answer 5

\(\sf C= 2 \pi r\) is right :)
you were given the radius and you are looking for circumference..plug them in

\(\sf C= 2 \pi r =2(3.14)(12 in)= 75\ in\)

hmmm.... are you sure you copied the right question?

Answer 6

huh yea I guess?

Answer 7

so c is correct

Answer 8

how did you get C though?

Answer 9

i'm getting 75 instead of 24

Answer 10

I guessed

Answer 11

those are the answer

Answer 12

Since the Diameter of a circle with radius 12 is 24 I'll assume that's what the problem is? Am I right?

Answer 13

i guess

Answer 14

"What is the exact circumference " -> that's what the problem is asking though ?

Answer 15

so my answer is 24 and that's how i get 75?

Answer 16

so its is c
