Visually estimate the circumference, in centimeters, of a circle when the diameter is 3.06 cm. Circumference (cm) (1ptS) b. Calculate the circumference, in centimeters, for d = 3.06 cm using the equation of the best-t line. Use the graph to ensure that this value is reasonable. Circumference (cm) (1pm) c. Compare the calculated circumference to the two visually interpolated values (Steps 2b and 6a). Briey discuss any discrepancies.
