an automobile with 0.310 m radius tires travels 75,000 km before wearing them out. how many revolutions do the tires make, neglecting any backing up and any change in radius due to wear?

Respuesta :

Total revolution by tires is 39473684.2 m.

Circumference = 2πr

r = radius, given = 0.310 m

Put this value in formula 2πr

Circumference = 2πr

Circumference = 1.9 m

Distance travelled = 75000 km = 75000000 m

Total revolution = (distance travelled) ÷ circumference

Total revolution = 39473684.2 m

Therefore, Total revolution is 39473684.2 m.
