This graph relates the radii of circles to their approximate circumferences.

Radii and Circumferences of Circles
On a coordinate plane, the x-axis is labeled Radius (in centimeters) and the y-axis is labeled Circumference (in centimeters). A line goes through points (0, 0), (1, 6.28) and (2, 12.56).

According to the graph, which must be true?
When the circumference is approximately 4 cm, the radius is 25.12 cm.
