The radius of a bicycle wheel is 12 in. What is the approximate circumference of the wheel?

Sagot :

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!
