Wheel I has diameter 21.7 in. Wheel II has diameter 20.5 in. Round the diameter of each wheel to the nearest inch. About how much farther will Wheel I travel in one rotation? Use 3.14 for π.
+36916 Wheel I rounded = 22" circumference = pi x dia = 22 x 3.14 = 69.08
Wheel II rounded = 21" pi x dia = 21 x 3.14 = 65.94 Difference = 3.14 " (pi)
