Answer: [tex]v=cd^3[/tex]

Step-by-step explanation:

The equation for direct variation between x and y (dependent variable) is given by :-

[tex]y=kx[/tex], where k is the proportionality constant.

Let the algebraic expression for the volume of sphere is v and for diameter is d.

The given statement : The volume of a sphere varies directly as the cube of its diameter.

Then the algebraic equation for the given statement will be :-

[tex]v=cd^3[/tex], where c is the proportionality constant.
