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

Well, the formula for circumference is: 

\(2πr\)

We already know that \(r=12\), and that \(π=3.14\)(Approximately), so we have everything we need. 

Substitute: 

\(2πr\)

\(=2(3.14)(12)\)

\(=(24)(3.14)\)

\(=75.36\)

The circumference of the bicycle wheel is approximately 75.36 inches. 

Hope this helped!
