radius r.
(b) Find an expression for the surface area S of the can based on the height h and the base
radius r. (Hint: The top and bottom of the can are circles of radius r and the side of
the can is really just a rectangle that has been bent into a cylinder.)
(c) Using the fact that V = 33.6, write S as a function of r and state its applied domain.
(d) Use your graphing calculator to ﬁnd the dimensions of the can which has minimal surface
area.
4. In Exercise 11 in Section 1.5, the population of Sasquatch in Portage County was modeled
by the function P (t) = t150t , where t = 0 represents the year 1803. When were there fewer
