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
30 if the answer.....................
.I am 100%shore
<span>The curve formed by a quadratic equation is called a PARABOLA</span>
The answer would be C) 0.733 because divide 11 and 15 and you get 0.733333 and since you wanted it rounded to nearest thousandth, its going to be 3 decimal spaces so remove the last three number 3's from the right and you end up with 0.733.
