If a bicycle wheel 156 cm in diameter rotates at 900 rev/sec, what is the speed of the bicycle in cm/sec? HELPPPP

OpenStudy (anonymous):

156cm in diameter = 156*pi cm in circumference 156*pi*900 is the answer

OpenStudy (anonymous):

how did this happened... @LS1088

OpenStudy (anonymous):

Eh? well because a bicycle wheel is circular every time it rotates once it travels distance equal to its circumference

OpenStudy (anonymous):

@LS1088 ah okay! :)

@LS1088 thanks by the way! :)
