Akari has a sink that is shaped like a half-sphere. The sink has a volume of 8000/3*π in^3. One day, her sink clogged. She has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when Akari begins scooping. Hint: you may need to find the volume for both. Cup A has a diameter of 4 in. and a height of 8 in. Find the Volume of Cup A.
Determine how many cups of water must Akari scoop out of the sink with Cup A to empty it? Round the number of scoops to the nearest whole number, and make certain to show your work.
Cup B has a diameter of 8 in. and a height of 8 in. Find the volume of Cup B.
How many cups of water must she scoop out of the sink with Cup B to empty it? Round the number of scoops to the nearest whole number, and make certain to show your work.
