If a automobile tire has a diameter of 36in.how many revolutions will the wheel make as the automobile travels 5 280ft?

Question

an automotive tire

Answer 1

The simpler way to answer this question is to know your measurements. 36 inches = 1 yard. 1760 yards = 1 mile. 5280 feet = 1 mile. Therefore, 5280 feet = 1760 yards. Answer= 1760 yards. Ask yourself if the lesson is testing your knowledge of radian measure, or is it testing you on your knowledge of unit conversions.

Answer 2

Hi! You will need to use the circumference formula to calculate revolutions.

 

C= 2(pi)r

 

You need r= radius. To calculate radius, divide the diameter by 2. 

36/2- 18in. 

 

C= 2(pi)18

C= 36(pi)

C= 36pi Inches

C= 113.0973

 

Convert inches to feet.

 

In one feet= 12in. So 36pi/12 = 3pi feet

 

Now we divide 5280/3pi = 1760pi revolutions. 

 

Final Answer: 

1760pi revolutions or 5529.20307 revolutions.
