Cylinders A, B, and C have the same radius but different heights. Put the cylinders in order of their volume from least to greatest.

• C

• B

• A

Two cylinders, a and b, each started with different amounts of water. The graph shows how the height of the water changed as the volume of water increased in each cylinder. Match the graphs of a and b to Cylinders P and Q.

Cylinder P (a)  

Cylinder Q (b)
