Question 287834
diameter of 1 meter means a radius of .5 meters.


circumference of the wheel is equal to 2*pi*r = 2*pi*.5 = pi = 3.141592654 meters.


1 cycle of the wheel rolling is equal to the circumference of the wheel.


26 cycles means the wheel has rolled the length of its circumference 26 times.


That equals to:


3.141592654 * 26 = 81.68140899 meters of rolling.


82 meters is the closest to 81.68140899 meters.
