Answer:
______________________________________________________
The circumference (in terms of "π") is: " 12π in. " .
__________________________________________________________
The circumference (using "3.14" as an approximation for "π") is: " 37.7 in. " .
__________________________________________________________
Circumference, "C" = π* d ; (d = diameter = 12 in.);
C = π* d = π * 12 in. = " 12π in. " (in terms of "π").
Or, using the approximation, "π ≈ 3.14" ;
C = 3.14 * (12 in.) = 37.68 inches ; round to: " 37.7 in. " .
