If the diameter of a circle is 2.5 and there is 5,280 ft in a mile how many times does the tire have to roll to get 1 mile

Answer 1

circumference of a circle = pid = pi times the diameter = 2.5pi feet around

= about 2.5 x 3.14159 = about 7.854 5280/7.854 = 672.3 time the tire rols

5280/2.5pi = 2112/pi =about 2112/3.14159 = about 672.3 tire rotations.
