Ali is exploring the formula for the circumference of a circle. He computed the circumferences of several circles with different radii. He then plotted the results and connected them with a line, as shown below. The graph shows the circumference (in cm) versus the radius (in cm). Find the mg; and the domain of the function shown. Circumference (cm) Radius (cm) Write your answers as inequalities, using x ory as appropriate. Or, you may instead click on "Empty set" or "All reals" as the answer.
