To solve for the indicated variable;
[tex]L=2\pi rh[/tex]
We shall solve for r as shown below;
[tex]\begin{gathered} L=2\pi rh \\ \text{Divide both sides by 2}\pi h\text{ to isolate the r variable;} \\ \frac{L}{2\pi h}=\frac{2\pi rh}{2\pi h} \\ \frac{L}{2\pi h}=r \end{gathered}[/tex]
ANSWER:
Therefore, the solution is;
[tex]r=\frac{L}{2\pi h}[/tex]
