a bicycle has a front wheel with a diameter of 24cm and a back wheel with a diameter of 60cm. through what angle does the front wheel turn if the back wheel turns through 12 radians
Answered by Reiny
distance covered by both wheels must be the same ...
with radians, arclength is simply rØ

so 24Ø = 60(12)
Ø = 30 radians
