We want to build a cylindrical can with total surface area of 100 square inches. this surface area includes the top and bottom of the can. find the dimensions of the can of this type that maximizes the volume of the can.

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
