A manufacturer is making a cylindrical can that will hold and dispense flower seeds through small holes in the top of the can. The manufacturer wants the can to have a volume of 42 cubic inches and be 6 inches tall. What should the diameter be?
Hint: Use the formula for Volume of a Cylinder: V = pi(r^2)(h), where V is the volume, r is the radius, and h is the height. Round your answer to the nearest inch. DON'T FORGET ABOUT UNITS!!!
