    First you don't have an area, you have a volume if it's cm^3

    Write the formula for the volume or surface area of a cylinder and make it equal 16pi

    Then rearrange to make h the subject of the formula

    Do you mean surface area or volume? As you've said area but states cm^3.

    Formula for volume: pi*r^2*h
    Formula for area: 2pi*r^2 + 2pi*r*h

    Depending on which your 16pi relates to you can set the formula equal to 16pi and rearrange.

    Edit: I was too slow lol

    so for that misunderstanding i meant volume! so:

    16pi*=pi*r^2h therefore pi* cancels leaving 16=r^2h !

    so does this give you a final answer of 16/r^2=h

    Yep, from what you've said the question was that seems perfect to me.
