Question

1.the diameter of a wheel is 98 CM. in how many revolutions will it cover a distance of 1540 m? ​

Answer 1

Answer: circumference of an wheel=πd

=22/7×98

22×14

=308cm =1 revolution

distance covered

1540×100=154000

now,154000÷308

500 rotations

Step-by-step explanation:

Answer 2

Answer:

revolutions will it cover a distance of 1540 m is 500 approximately.

Step-by-step explanation:

Given:

The diameter of a wheel is 98 CM.

Then, the radius of the wheel =98/2=49 cm.

now,

Perimeter of the wheel

=(2π)x(radius of the wheel)

=2x3.142x49

=307.88 Cm

Therefore, revolutions will it cover a distance of 1540 m =(1540x100)/307.88

=500.20

=500 (approximately)
