What are the formulas for the volume of a cylinder, cone, sphere, and pyramid? What if you knew the volume of a shape, but you were missing one of the shape's measurements - how could you figure out the missing value? How do you know which measurement, for example on a cylinder, is the height versus the radius? Where do you look for the radius on a cylinder, cone or sphere? What is the difference between radius and diameter?

How did you know which formula to choose when it was a missing side you had to solve for rather than the total volume? Can you explain how those formulas came about? Were there any hints in those formulas that clued you into choosing one over the rest? If you enter values in a different order than in the given volume formula, would you get the same value? Which formulas would this work for, and which would it not? How can you use the volume formula to find a missing radius or height? What could be a formula for the height of a cylinder, cone, or sphere?
