Heya !!
Here's your answer.. ⬇⬇
♦ Given :- diameter = 49cm
radius = 49/2
Distance travel by train = 154m
♦ To Find :- Revolution make by wheel.
♦ Solution :- One Revolution of wheel = Circumference of wheel = 2πr
= 2 × 22/7 × 49/2
= 154cm
Total Distance travel by train = 154m
1m = 100cm
154m = 15400cm
Dividing total distance by distance covered by one revolution we get no. of Revolutions.
No. of Revolutions = Total distance/ distance covered by one revolution.
= 15400/154
= 100
So, The wheel of train makes 100 revolutions
Hope it helps..
Thanks (:
