Shannon's scooter has a piece of tape stuck to the tire. If the tire has a diameter of 18 inches, how far does the piece of tape travel in 72° of rotation?

Question

anonymous · Answer

well the circumference of a circle in terms of diameter is 

C=π×d


the tape will travel the circumference of the tire... so find the circumference

anonymous · Answer

how? I'm really bad at it, can you show me?

anonymous · Answer

ok so the circumference of the tire is 

C=18π


what fraction of a circle is 72 degrees

72360


so the distance traveled is the circumference x the fraction... 

72360×18π


you'll need to simplify the answer

it will be 18π over 5
