A paper drinking cup is being
designed in the shape shown in the accompanying figure.
The amount of paper needed to manufacture the cup is
determined by the surface area S of the cup, which is
given by s=πr√(r^(2))+h^(2)
where r is the radius and h is the height.
(b) Could the formula for S be simplified as follows?
πr√(r^(2))+h^(2)=πr(√(r^(2))+√(h^(2)))=πr(r+h)
