1. Which of the following graphs could represent the volume of water in a cylinder as a function of its height? Select the correct choice

The volume of a cylinder is:
[tex]V=h\cdot\pi\cdot r^2[/tex]Where:
V = volume;
h = height;
r = radius.
So, as can be observed, the volume and the height have a linear relation.
Thus, the graph of a line represents this function.
Answer: Graph A.
