"WebFor the partial derivative with respect to h we hold r constant: f’ h = π r 2 (1)= π r 2. (π and r2 are constants, and the derivative of h with respect to h is 1) It says "as only the height changes (by the tiniest amount), the volume changes by π r 2 ". It is like we add the thinnest disk on top with a circle's area of π r 2. " - Solving partial differential equations with r
