Hi franklin91,

Find the circumference of the wheel. C= Pi times the diameter = 32 Pi inches

Find out how many inches in 9 miles. 9 times 5280 ft times 12 inches = 570240 inches.

Divide the number of inches in 9 miles by the circumference of the wheel. 570240 / (32 Pi) = 5672.3 revolutions.

thank you so much....i really appreciate it

Divide the number of inches in 9 miles by the circumference of the wheel.
570240 / (32 Pi) = 5672.3 revolutions.[/size]

...and you'll get a flat during the final .3 revolution...

there 3.67 miles to your grandparents’ home and u got If the circumference of each wheel on your bicycle is 82.6 inches, how many revolutions of a bicycle wheel will it take to get to your grandparents’ home?
