what is the ratio of the volume of a sphere to its surface area

The ratio of the volume of a sphere to its surface area can be represented by the formula:

Volume/ Surface Area = (4/3) * π * r^3 / 4 * π * r^2
Volume/ Surface Area = (4/3) * r

Therefore, the ratio of the volume of a sphere to its surface area is 4/3, regardless of the size of the sphere.
