1188 = π<em>r</em>²<em>h</em>
For the formula to solve for <em>h, </em>you have to change the equation to:
<em>h </em>= 1188/π<em>r</em>²
which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.
because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)
Since you don't know the radius, you can't simplify this equation.
The answer is <em>h </em>= 1188/π<em>r</em>²
