Answer:
C = 37.7 inches
Step-by-step explanation:
You are looking for the circumference.
Formula for the circumference-> C=2πr
variables:
c = circumference
r = radius
You have the diameter, which is 12 inches. Radius is half of the diameter. which means r is half of 12 (aka 6).
put the radius where the variable is in the formula.
C=2π(6)
you now have enough information to solve for circumference.
C = 2 * π * 6
C = 37.7
