radius of wheel = 42cm
in 1 revolution distance covered = 2πr = 2×22/7×42=264
.'. in 400 revolutions the distance
covered will be =400 ×264
=1,05,600
here's ya answer ....

As we know that the Circumference of Circle= 2 x Pi x r
Pi= 22/7
2 x 22/7 x 42
=2 x 22 x 6
=44 x 6
= 264
Therefore, Circumference of Circle is 264 cm
264 x 400= Distance covered by wheel
=105600 cm / 1056 m / 1.56 km
