The radius of a tire is 1.2 feet. How far will you travel after ten complete rotations of the tire?

Montano1993 [528]

Well you have to start of by finding the circumference of the tire, which you can do with the equation 2πr. If the radius is 1.2 feet, you just plug this into the equation to get 2.4π, which we will round to 7.5. After 10 rotations, you should've traveled approximately 75 feet
