Question

Solve the problem as directed.

Answer 1

The algebraic equation for the given statement is $v = cd^3$

Solution:

Given that The volume (v) of a sphere varies directly as the cube of its diameter (d)

To find: statement in algebraic language using an equation with the variables c, v, and d

Let "v" be the volume of sphere

Let "d" be the diameter of sphere

From given information,

volume of sphere varies directly as the cube of its diameter

$\text{ volume of sphere } \alpha \text{ cube of its diameter}$

$\text{ v} \alpha d^3$

$v = cd^3$

Where "c" is the constant of proportionality

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

$v=cd^3$ , where c is the proportionality constant.
