×rmeters

⇒ Distance covered by the wheels in one revolution = 2×

22

×rmeters

⇒ Distance covered by the wheels in 450 revolutions = 2×

22

×r×450meters

It is given that the car travels 1 kilometer i.e. 1000 meter distance when its each wheel makes 450 revolutions.

⇒2×

22

×r×450=1000

⇒r=

2×22×450

7×1000

⇒r=0.3535meters

∴r=35.35cm
