Question

Diameter of wheel of bus is 1.8 meter.How many rotation will a wheel complete while travelling a distance of 50 km...plz solve it with method dont give only answer!!!plz​

Answer 1

Answer:

let, wheel is in the form of circle.

Diameter of circle is 1.8 m

Radius of circle is D/2

r = 0.9 m

Total distance to complete 50 km

thai is 50000 m

No. of total rotation to complete 50 km is -- Circumference of wheel is 2πr

= 2 × 22/7 × 0.9 m

= 39.6/7 m

No. of total rotation to complete 50 km is -

= total distance to cover by bus / circumference of circle or wheel of bus

= 50000 / 39.6 / 7 m

=8838.38 rotation
