Step-by-step explanation:
Given:-
The diameter = 50 cm
so radius=50/2
So the distance travelled by the car in one revolution = it's circumference
i.e
circumference=2πr
= 2 × 22/7 × 50/2
=2×11/7×50
=2×550/7
=2×78.57
=157.14cm
Therefore distance covered in 100 revolutions.
=157.14×100
=15714cm
or 157.14m
