Step-by-step explanation:
given diameter = 49cm
then radius = d/2 = 49/2 = 24.5 cm
r = 24.5cm
from the formula....
no. of revolutions = distance / circumference of
a wheel
given revolutions = 100
circumference = 2πr
no of revolutions = distance / circumference of wheel
100 = distance /2πr
100 = distance / 2 × 22/7 × 24.5
100 = distance/(1078/7)
100 = distance/ 154
distance = 154 × 100
distance = 15400
distance = 15400cm
