A) The formula for the volume of a sphere in terms of its radius (half the diameter) is

For your 18 cm sphere, the volume is

B) If the diameter were reduced by half, the volume would be

of the original volume.
To get the inverse "relation" of an expression, we first off, do a quick switcharoo of the variables, and then solve for "y", so let's proceed,
