Question

Radius of a wheel is 0.25 meter. Find the number of revolutions to cover the
distance of 11 km by it

Answer 1

Radius = 0.25 m

Circumference of the wheel = 2πr

= 2 × 3.14 × 0.25

= 2 × 22/7 × 0.25

= 44/7 × 0.25

= 11/7

Total distance = 11 km = 11000 m

No.of revolutions = 11000 × 11/7

= 11000 × 7/11

= 7000

Answer 2

Answer:

7000

Step-by-step explanation:

Radius of the wheel= 0.25 cm

Circumference= 2 πr

= 2*22/7*0.25

=11/7

Total distance= 11 km = 11000 m

Number of revolution=11000/11*7

= 7000
