Answer:
you are looking for the circumference. which is C(circumference)= x r (radius)
the radius is =to half of the diameter.
c=56.55
Step-by-step explanation:
circumference=distance around
C=pid
d=diameter
pi=3.14 approx for t his question
given
diameter=18
C=18*3.14
C=56.52 in
length around is 56.52 inn
