A cylindrical vase has a diameter of 4 inches. At the bottom of the vase, there are 6 marbles, each of diameter 3 inches. The vase is filled with water up to a height of 8 inches. Which of the following could be used to calculate the volume of water in the vase?

π(2in)2(8in) − 6(four over threeπ(1.5in)3)

Step-by-step explanation:

Explanation:

First you need to know the volume of a cylinder which is V= π r^2h

Then you plug the question into the volume equation giving us V = 3.14*(2^2)*8

(the radius is 2 because the diameter (4) can be split in half)

The only ones matching that explanation is A and C

Finally A is the answer because the 6 marbles were mentioned first so that gives us A

answer: i think it is c
