Question

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

Answer 1

The volume of a cylinder is:

`V=h\cdot\pi\cdot r^2`

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.
