Find the number of rotations a vehicle whose wheels are 30 inches in diameter will make over a distance of 12 miles.

C={π}. D, D=30 and π=3.14

C=3.14. (30)

C=94.2 inches

How many inches in 1 mile

1 mile = 5280 feet

1 foot = 12 inches

1 mile = 5280 ft

1 mile = 63,360 inches

12 mile = 63,360*12

=760,320/94.2

= 8,071.33/revolution
