The \(x\)-axis of each graph has the diameter of a circle in meters. Label the \(y\)-axis on each graph with the appropriate measurement of a circle:
radius (m), circumference (m), or area (m²).

First of three graphs. Horizontal axis, diameter in meters, scale 0 to 10, by 2's. Vertical axis, scale 0 to 20, by 2's. First graph is curved upward from left to right, begins at the origin, passes through 2 comma 3, 3 comma 7, 4 comma 12, 5 comma 19.

Second of three graphs. Horizontal axis, diameter in meters, scale 0 to 10, by 2's. Vertical axis, scale 0 to 20, by 2's. Second graph is a upward line from left to right, begins at the origin, passes through 2 comma 1, 4 comma 2, 6 comma 3, 8 comma 4.

Third of three graphs. Horizontal axis, diameter in meters, scale 0 to 10, by 2's. Vertical axis, scale 0 to 20, by 2's. Third graph is a upward line from left to right, begins at the origin, passes through 2 comma approximately 6 and 28 hundredths, 4 comma approximately 12 and 56 hundredths, 6 comma 18 and 84 hundredths.
