Question

The diameter of wheel is 84cm. find the distance travelled in km by it after 500 evolution.

Answer 1

Answer:

Distance travelled in km = 1.32 km

Step-by-step explanation:

Diameter = 84 cm

Radius = 42 cm

Circumference = 2πr

= 2*22/7*42

= 264 cm

Number of revolutions = 500

Distance covered = 264*500

= 132000cm

Distance in km = 132000/100000

= 1.32 km
