Sensitivity Analysis of a Cylinder's Volume

Functions and graphs warmup

A cylindrical steel storage tank is to be built that is 10ft tall and 4ft across in diameter. It is known that the steel will expand/contract with temperature changes; is the overall volume of the tank more sensitive to changes in the diameter or in the height of the tank?

What this problem tests

Tests the ability to compute partial derivatives, construct a total differential, and interpret the coefficients as sensitivities.

This is a classic application of partial derivatives in a multivariable calculus course, demonstrating how the total differential can be used for sensitivity analysis or error propagation.
