hey mate.
Distance = no of revolutions × circumference of a wheel
=) 176m = n × 22/7 × 40cm
=) 176 × 100 × 7 / 22*40 = n
=) 140 = n

Answer:
Option(A)
Step-by-step explanation:
Given, diameter = 40 cm.
Given, distance = 176 m = 17600 cm.
Circumference of wheel = πd =
= (22/7) * 40
= 880/7 cm.
So,the distance covered in 1 revolution = 880/7 cm.
Therefore, total number of revolutions:
= 176m/πd
= (176 * 7 * 100)/880
= 140
=
Hope it helps!
