Yes you used the chain rule properly to follow the correct steps to get the right answer. Great job.
If you wanted, you can come up with examples for f(x) and g(x) to help confirm the answer. A quick way to do this is to use something like GeoGebra to help graph the two expressions and you'll notice that the curves match up perfectly (indicating equivalent expressions). Note: GeoGebra can handle derivatives through the Derivative[] comand or you can type the function in the input bar with a tickmark after it to tell GeoGebra to derive the function.

Step-by-step explanation:

This is actually the correct answer after I solved it continuously
Answer: The base area, diameter, and radius can be found out by discovering the volume and height. Substitute the values to the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable to find the diameter which is double the radius.
