Answer:

C = 2 π r

Step-by-step explanation:

Your answer is 2 pi/π r.

The formula of a circumference is always 2 pi r.

18 x 3.14 x 2 = 113.04

in this case radius is 18

pi is 3.14

2 is just always there when finding out circumference.

Answer:

113.04 (estimated)

Step-by-step explanation:

I used the formula that includes pi.

basically multiply the radius by 2 and multiply the answer with π or 3.14 for the estimation.
