Awheel has a diameter of 3.5ft. approximately how far does it travel if it makes 20 complete revolutions? use 22/7 for pi.

If the wheel doesn't slip or skid, then every time it makes
a revolution, it travels the circumference of the wheel.

If its diameter is 3.5 ft, then its circumference is  (3.5 pi)

                   = (3.5 ft) x (22/7)  =  77/7 ft  =  11 ft .

In 20 complete revolutions, it travels

                   (20) x (11 ft)  =  220 ft .
