A wheel has a diameter of 21 inches. Approximately how far does it travel in 3 revolutions?

RideAnS [48]

So each 1 revolution it travels the distance around the rim of the wheele aka circumference
circumference=pi times diameter
diameter=21
circunference=pi times 21 or 21pi
so distance=number of revolutions times circunference
number of revolutions=3
subsitute

distance=3 times 21pi
distance=63pi

answer is 63pi
or aprox pi to 3.14 and do 63 times 3.14=197.82
aprox 197.82 inches
