Question

The diameter of a wheel of a bus is 90 cm how many revolutions will it make to travel 110 km

Answer 1

110 km into cm = 11000000
R= 45
so perimeter= 2π*45= 2*22/7*45=282.85cm
so for 110 km= 11000000/282.85=38889.87
so it will take 38889 complete revolutions
hope you got your answer

Answer 2

Dear Student,

◆ Answer -

No of revolutions is 38889

● Explaination -

Circumference of the circle is -

Circumference = πd

Circumference = 22/7 × 90

Circumference = 1980/7 cm

No of revolutions is taken to travel 110 km = 11×10^6 cm is

No of revolutions = 11×10^6 / (1980/7)

No of revolutions = 38889

Hence, no of revolutions are 38889.

Thanks dear for asking. Hope this helps you...
