Question

the radius of A wheel of a bus is 0.35 metre how many rotations will a wheel complete while travelling a distance of 22 km​

Answer 1

Step-by-step explanation:

Total Distance = Circumference × No. of Rotation

• PUT THE VALUE IN THE FORMULA

22 km = 2*π*(0.35m) × No. of Rotation

• CONVERT ALL THE UNIT AS METRE
• Take [π = 22/7]

22000 m = 2*22/7*(0.35m) × No. of Rotation

1000 = 2*0.05 × No. of Rotation

100000 = 10 × No. of Rotation

No. of Rotation = 10,000
