Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
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.
Your answer is selection b.
