The formula for the circumference of a circle is C=πd About how much farther will a bicycle with a 27-inch-diameter wheel travel in one complete rotation than a bicycle with a 25-inch-diameter wheel?

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
