Asked by Harry
Jane got so annoyed at Frank playing a song on a cd that she decided to throw it under her car and run over it. The CD has a diameter of 12cm and the wheel
has a diameter of 54cm. How many degrees does the wheel of her car need to turn to run over the CD? (Round to nearest whole number)
Thanks Oobleck for answering my other question.

s = rθ
so, you have
54/2 θ = 12
θ = 4/9 radians = 4/9 * 180/π = 80/π = 25.46°
