The volume of a sphere is found using the formula V=4/3 \pir^3 The area of a circle is found using the formula A= \pir^2. What is the ratio of the volume to the area?
To get the ratio between the volume and area of a sphere, divide V = 4πr^3/3 by A = πr^2. Since π appears in both equations, it will be eliminated. r^3 divided by r^2 is r. Thus, the ratio of volume to area is 4r/3.
