Using Models Use the model given to answer the questions about the object or process being modeled. The volume $V$ of a cylindrical can is modeled by the formula $$V=\pi r^{2} h$$ where $r$ is the radius and $h$ is the height of the can. Find the volume of a can with radius 3 in. and height 5 in.

Modeling the Real World with Algebra
Use the model given to answer the questions about the object or process being modeled. The volume $V$ of a cylindrical can is modeled by the formula $$ V=\pi r^{2} h $$ where $r$ is the radius and $h$ is the height of the can. Find the volume of a can with radius 3 in. and height 5 in.
In the problem you are asked to find a function that models a real life situation. Use the principles of modeling described in this Focus to help you. The height of a cylinder is four times its radius. Find a function that models the volume V of the cylinder in terms of its radius r.
