Solve for the indicated variable. Include all of your work in your answer. Submit your solution.C = 2r; for r

1. Break Down the Problem

We need to solve the equation $C = 2r$ for the variable $r$. This means isolating $r$ on one side of the equation.

2. Relevant Concepts

To solve for $r$, we can use algebraic manipulation. The goal is to get $r$ by itself on one side of the equation.

3. Analysis and Detail

Starting with the equation: $C = 2r$

To isolate $r$, we can divide both sides of the equation by 2: $r = \frac{C}{2}$

4. Verify and Summarize

To double-check, we can substitute back $r$ into the original equation: $C = 2 \left(\frac{C}{2}\right) = C$ This confirms our solution is correct.

Final Answer

The solution for $r$ is given by: $r = \frac{C}{2}$
