V.2 Why does it work?


Dry oatmeal comes in a cylindrical container with a radius of 2 in. and a height of 5 in.

Figure out how much oatmeal can fit in the container.

Damien's "Substitution" Method
I label the height and radius so I know what to put in the formula.
I remember the volume formula for a cylinder!
I substitute the values into the formula and calculate.
V = πr2h
V = π(2)2(5)
V = π(4)(5)
V = 20π in.3
