was studying for my Maths final and this came up in a 1996 exam paper.
The top and bottom of a cylindrical tank are made of sheet metal weighing 3 kgs per square meter, and the sides are made of a thinner material that weighs 1.5 kgs per square meter. The radius is 1.2m and the height is 1.6m
If the raduys was uncreased by 3% and the height was decreased by 5%, use the formula
ΔW=[itex]\frac{∂W}{∂r}[/itex]Δr+[itex]\frac{∂W}{∂h}[/itex]Δh
to estimate the change in weight.
Thanks guys.
