9. We want to construct a cylindrical can with a bottom but up that will have a volume of 300m3 . Determine the dimensions (radius 7' and height h) of the can that will minimize the amount of material needed to construct the can (total surface area). The volume of the can is V = zrrzh . Round answers to 2 decimal places. 10. A professional pitcher on the ground throws a ball upward at a speed of 100 /s.
