With your vast powers, you create an innite paint can by revolving the
curve y = 1
x from x = 1 to 1 about the x-axis.
1) Find how much paint the can will hold, i.e., nd the volume of the can.
2) Calculate how much paint it will take to coat the sides of the can, i.e., nd
the surface area of the can. See the formula on page 571 (area of a surface
of revolution).
3) Are your answers to parts 1) and 2) consistent? If not, try to explain
what is going wrong.
