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

Distance = No. of revolutions × Circumference of wheel
= 2000 × 2 π × (0.63/2 m)
= 3960 m
= 3.96 km

∴ Car will move a distance of 3.96 km

Answer 2

Answer:

395840 cm

Step-by-step explanation:

Diameter of wheel = 63 cm

Radius of wheel = $\frac{Diameter}{2} =\frac{63}{2} =31.5$

Circumference of wheel = $2\pi \times r$

                                       = $2\pi \times 31.5$

                                      = $197.92$

thus distance travel in 1 revolution = 197.92 cm

So, distance travel in 2000 revolution= $197.92*2000=395840$

Hence the distance travel in 2000 revolution is 395840 cm
