## Homework Statement

Use the differential to estimate the volume of tin a can of radius 4 cm., height 12 cm.

and thickness 0.04 cm is made of.

## Homework Equations

(differential)

df = f'(x,y)dx + f'(x,y)dy

The approximated volume should be 14cm^3. However, I need the procedure to get to the result (since it was given).

## The Attempt at a Solution

I know how to compute the differential. In order to do so I need the two derivatives in x and y. then the formula is straight forward: df = f'(x,y)dx + f'(x,y)dy

Unfortunately I have no clue how to apply this concept to solve the problem.

Any help would be appreciated.
