Question

how many times will the wheel of a car rotate in a journey of 2002 metres, if it is known that the radius of the wheel is 49 CM? ​

Answer 1

Circumference = 2πr

                         = 2 x 22/7 x 49

                         = 308 cm

Length of Road = 2002m = 200200cm

Times the wheel will rotate = Length of road / Circumference

                                              = 200200/308

                                              = 650 times
