Best ResponseYou've already chosen the best response.1Let's find the volume of water you can fit in the vase if there are no marbles in it. The vase is a cylinder of diameter 6 inches and height 10 inches. Can you calculate the volume of such a cylinder?

Best ResponseYou've already chosen the best response.1Correct. Now by putting 10 marbles in the vase, the vase will not be able to hold as much water. The amount of water volume that will be reduced is the same as the combined volume of all the marbles. Each marble is a sphere. What is the volume of a sphere with diameter 3 inches?

Best ResponseYou've already chosen the best response.1Look carefully. In choice c., 10 in is squared in the cylinder formula. In the problem, 10 in. is the height. It is the 3 in. radius that is squared.
