Anthony has a sink that is shaped like a half-sphere. The sink has a volume of 4000/3*π in^3. One day, his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when Anthony begins scooping. Hint: you may need to find the volume for both.

1.)One cup has a diameter of 4 in. and a height of 8 in. How many cups of water must Anthony scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number, and make certain to show your work.
