A ) 49π m
B ) 48π m
C ) 43π m
D ) 47π m

Steps to derive

1 Diameter of the cart wheel is 4.3 m
 [Given.]

2 Circumference of the wheel = 4.3π
 [Circumference = πd.]

3 Distance covered for 10 revolutions = 10 × 4.3π = 43π m.
 [Distance covered = circumference × no. of revolutions.]



Hence the right answer is Option C
