There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches. Item at position 10 10 1 point Is there a linear relationship between the radius and the volume of these cylinders? How do you know? Yes, because when the points are plotted, they form a straight line. Yes, because the pairs of points have a constant rate of change. No, because the slope between the pairs of points is not the same. No, because there is more than one output for each allowable input.
