Question

If the diameterof a wheel of a truck is 98cm,what is the distence covered by wheel in1500 revolutions

Answer 1

Radius = 98/2  cm

           = 49   cm

Circumference = 2*(22/7)*49  cm

                        = 2* 22 * 7  cm

                        = 44*7  cm

                        = 308 cm

So, the distance covered by the wheel in 1500 revolutions = (1500*308)cm

                                                                                                  =462000 cm

                                                 = (462000/100000) km [100000 cm = 1 km ]

                                                = 4.62 km

(Ans): 462000 cm or 4.62 km.
