56.52 in





113.04 in

Answer 1

@k_lynn

Answer 2

\[C=2πr\]

Answer 3

divide 18/2 to get the radius

Answer 4

and plug it into the formula

Answer 5

9

Answer 6

Around the rim would mean to find the circumference. And we went over what that formula was which was \[C=2\Pi r\]But you know the diameter which is DOUBLE the radius. You'll need to divide the diameter by 2.

Answer 7

@Sunnyo now plug it in

Answer 8

Yep, the radius is 9. We also know what pi is. So we just plug the numbers into the equation.
\[2\times3.14\times9\]

Answer 9

\[C=2π(9)\]

Answer 10

56.52

Answer 11

\[\Pi=3.14\]
\[r=radius=9\]

Answer 12

well they said what i was gonna say

Answer 13

Yep @Sunnyo You got it! :D Great job!
