10.1 1 Review Identify two reasons why a cell’s growth is limited Explain As a cell’s size increases, what happens to the ration of its surface area to volume ratio Applying Concepts Why is a cell’s surface to volume ratio important 2 Visual Thinking The formula for finding the surface of area of a sphere is A=4πr2. The formula for finding the volume of a sphere is V=4/3r3. Calculate the surface area and the volume for the baseball and basketball. Then write the ratio of surface are to volume for each. Baseball r = 3.6 cm Basketball r = 12.2 cm
