Acylindrical vase has a diameter of 6 inches. at the bottom of the vase, there are 7 marbles, each of diameter 3 inches. the vase is filled with water up to a height of 12 inches. which of the following could be used to calculate the volume of water in the vase?

R = 3 =base vase
r = 1.5 = marble
volume marble = 4/3×pie×1.5^3
= 14.1372in^3
water = 12

volume vase without marble = pie × r^2 x h
= pie × 3^2 × 12
= 339.2920in^3

volume water = 339.2920 - 14.1372
= 325.1548in^3

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
