Question

Solve the following formula for the indicated variable.L = 2nrh; solve for r.

Answer 1

To solve for the indicated variable;

`L=2\pi rh`

We shall solve for r as shown below;

`\begin{gathered} L=2\pi rh \\ \text{Divide both sides by 2}\pi h\text{ to isolate the r variable;} \\ (L)/(2\pi h)=(2\pi rh)/(2\pi h) \\ (L)/(2\pi h)=r \end{gathered}`

ANSWER:

Therefore, the solution is;

`r=(L)/(2\pi h)`
