Question

Find the distance covered by the wheel of a bus in 2000 rotations if the diameter of the wheel is 105cm​

Answer 1

Diameter of wheel=105cm
Radius=105/2cm
Circumference of wheel= 2 pie r
=2 x 22/7 x 105/2
= 21x22
= 462cm

No. Of revolutions=2000
Area covered=2000 x 462
=924000cm2

Answer 2

Answer:

6.594km

Step-by-step explanation:

Diameter = 105cm

Radius = 52.5cm

Circumference = 2 π r

= 2 × 3.14 × 52.5

= 329.7cm

Therefore,

1 rotation = 329.7cm

2000 rotations = 329.7 × 2000

= 659,400cm

1m = 100cm

1km = 1000m

Therefore,

659,400cm = 6.594km

Therefore, the distance covered by the wheel of a bus in 2000 rotations if the diameter of the wheel is 105cm is 6.594km away...
