Question 837804
A tire that has diameter of 20 has circumference = {{{(pi)20}}}
So {{{(pi)20}}} is the distance traveled with one tire revolution.
1 mile / {{{(pi)20}}} will give us the number of rotations.
To work this we need to convert 1 mile to inches.
Since one mile is 5280 ft, one mile = 5280 * 12 inches
1 mile = 63360
The number of rotations = {{{63360/((pi)20)}}} = {{{3168/((pi))}}}
approximately 1008.4057 rotations
