adi1568: ok i found the mistake
adi1568: while converting the circumference of wheele instead of dividing it by 100 i just mutiplied it by 100
adi1568: so if u divide it by 100 you will get 0.66m
adi1568: and then if you furthur solve your answer will be 18750 revolutions which is the correct answer
