Well, the formula for circumference is:  [latex]2πr[/latex] We already know that [latex]r=12[/latex], and that [latex]π=3.14[/latex](Approximately), so we have everything we need.  Substitute:  [latex]2πr[/latex] [latex]=2(3.14)(12)[/latex] [latex]=(24)(3.14)[/latex] [latex]=75.36[/latex] The circumference of the bicycle wheel is approximately 75.36 inches.  Hope this helped! ~Cam943, Junior Moderator
