Question 871178: A car's wheels are 20 in. in diameter. How far (in miles) will the car travel if its wheels revolve 10,000 times without slipping? (Round your answer to two decimal places). Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! How many inches does the car wheel travel per each revolution?
Find the circumference.
Pi * diameter
Using 3.14159 for Pi = 62.8318
Multiply by 10,000 revolutions for a total distance of 628,318 inches
How many inches in a mile?
5280 feet * 12" = 63360
Divide total distance 628318 by distance in a mile 63360 to get:
9.92 miles
.
Note: There is the process. You will get slightly different numbers depending upon how many decimal places you take Pi to.
