The formula V = kr4 is used to predict how much the radius of a partially clogged artery has to be expanded to restore normal flow. In the formula, V is the volume of fluid flowing through a small pipe or tube in a unit of time at a fixed pressure, k is a constant, and r is the tube's radius. Which of the following approximates the increase in the flow (in cubic units) if r is increased from 1 unit to 1.1 unit?
