The formula for the volume, v, of a cone having the radius, r, and the height, h, is shown below. write the formula to calculate the height, h.

Solving for a variable is an illustration of changing the subject of formula

The formula to calculate h is:

The volume of a cone is:

Multiply both sides by 3

Divide both sides of the equation by

So, we have:

Rewrite as:

Hence, the formula to calculate h is:
