Each revolution moves the car pi*D = 6.283 feet
62000 miles is 327,360,000 feet
The number of revolutions is 5.210*10^7.
The number of radians is 2 pi times that... over 300 million
Hi! so you mean I have take 5.210*10^7 mutilply by 2 pi and than divide by 300 million. Just want to clarify thank you.

When I wrote "over 300 million", I was giving you an estimate of the number of radians. You do NOT divide by 300 million.
