$$v=\Pi r^2 h$$

anonymous · Answer

Correct.  So you can cross off the last two right off the bat.

anonymous · Answer

The general scheme for calculating volumes of simple objects is $$\text{Volume} = \text{Base Area} \times \text{Height}$$What are the (circular) base area and height of the cylinder?

anonymous · Answer

idk?
