(((Pleasee help asap! Giving brainliest))) A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 9 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? (6 points)

Select one:

a. π(3in)2(12in) − 1.5( four over three π(9in)3)

b. π(12in)2(3in) − 1.5( four over three π(9in)3)

c. π(3in)2(12in) − 9( four over three π(1.5in)3)

d. π(12in)2(3in) − 9( four over three π(1.5in)3)

Step-by-step explanation:

The volume of water in the vase is the difference of volume of cylinder and that of the marbles.  

           Vcylinder = πr²h = π(6 in)²(12 in) = 432π in³

           Vmarbles = 9(4πr³/3) = 9(4π(3 in)³/3) = 324 π in³

The difference of the volumes is 108π in³.

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
