Question

find the distance covered by the wheel of a car in 500 revolution if diameter of the wheel is 77 cm​

Answer 1

Distance covered in 1 revolution = πd = (22/7)*77 = 242cm

Distance covered in 500 revolution = 242cm*500 = 121000cm = 1.21km

Answer 2

Step-by-step explanation:

distance covered in 1 revolution = circumference

circumference = πd

22/7×77= 242 cm

therefore distance covered in 500 revolution

= circumference × no.revolutions

= 242×500

= 121000cm .
