Question

the diameter of every wheel of a car is 63 cm. How much distance will the car move during 2000 revolutions of its wheel.

Answer 1

Answer:

Step-by-step explanation:

give data,

radius= 63/2

circumference =2pi r

                        =2* 22/7 * 63/2

                         =198 cm ²

1 revolution took 198 cm²

then 2000 revolutions = 2000× 198

                                     =396000 cm²

                                      =3960 m²

                                     =0.396 km
