Problem 45 of 7
Rearrange V = pi * r^2 * h for cylinder volume to solve for r, choosing the meaningful branch for the context.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
apply square/square-root operations and choose meaningful branch.
Hidden until you reveal it.
Target must be inside a power or root relationship with a context branch.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Undo the power using the corresponding root.
2. Use the context to choose the meaningful branch, usually nonnegative for lengths.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Plus/minus branch when context is length and asks meaningful branch.
