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