Optimization of Cylinder Production Costs

The video tutorial explains how to construct a cylinder-shaped can to hold 300 cubic centimeters of soup while minimizing production costs. It covers the calculation of the volume and surface area, the setup of a cost function, and the use of calculus to find the dimensions that minimize costs. The process involves substituting variables, simplifying equations, and verifying results using derivative tests.

How is the height of the cylinder expressed in terms of the radius using the volume constraint?

• H = 300/πr²

• H = πr²/300

• H = 300πr²
