A cylindrical vase has a diameter of 6 inches. At the bottom of the vase there are eight marbles, each of diameter 3 inches. The base is filled with water up to a height of 10 inches. Which of the following could be used to calculate volume of water in the vase?

Volume of water in vase: 747in^3

Area of the base of the vase:

(pi)(r)^2= (pi)(6)^2 = 113in^2 (approx)

Volume of the marbles:

4/3 (pi)(r)^3 = 4/3(pi)(3)^3 = 85 (approx)

85*7= 609in^3

Volume of the water in vase:

113*12 = 1356

1356-609 = 747in^3
