The diameter of a car's wheel is 63 cm. Calculate the distance the car travels when the wheel completes 1000 revolutions.
Show answer & explanation
Correct answer: A
Explanation
Diameter of the wheel = 63 cm
Number of revolutions = 1000
Circumference = πd
Distance covered in one revolution cm
Distance covered in 1000 revolutions = 198 × 1000 = 198,000 cm
In kilometers = 198,000 / 100,000 = 1.98 km
