Radius equals diameter divided by two : Radius=42 inches/2=21 inches.
::If the circumference were 42 inches, we get the radius from the formula circumference equals two times radius times pi, hence
radius equal circumference divided by two pi, here twenty-one through pi, hence 21/3.1415 approx, 6,68 inches.
