Question

find the distance covered by the wheel of a bus in 2000 rotations, if the diameter of the wheel is 98 cm.

Answer 1

Hi ,

Let the diameter of a wheel = d = 98 cm

Distance covered by one rotation = circumference of a wheel

= π d

Distance covered by 2000 rotations

= 2000 × π d

= 2000 × ( 22/7 ) × 98

= 616000 cm

Or

= 6160 m

I hope this helps you.

Answer 2

Hiiii friend,

Diameter of the wheel = 98 cm

Radius of the wheel = D/2 = 98/2 = 49 cm


Distance covered by wheel in one rotation = Circumference of wheel = 2πR = 2× 22/7 × 49 = 44 × 7 = 308 cm²


Therefore,


Distance covered by wheel in 2000 rotations = 2000 × 308 = 616000 cm².



HOPE IT WILL HELP YOU....... :-)
