PLEASE be fast, middle school math -algebra honors

The graph shows how the velocity v in centimeters per second of a fluid flowing in a pipe varies according to the radius r of the pipe.

Find the velocity of the fluid when the radius is 3 cm.

When the radius of the pipe is 3 cm, the velocity of the fluid in the pipe is ________ cm/s

Answer 1

27 cm/s

Explanation:

The x-axis is labelled as radius (r). Since the question is asking you to find the velocity of the fluid, which is labelled on the y-axis, you simply need to move along the x-axis until you reach 3 cm and move upwards until you've reached the line. Once you have reached the line, the answer should be on the y-axis which is 27 cm/s.

*x-axis is along the bottom and y-axis is vertical along the left side.*
