Answer 1

Have you found the answer?

Answer 2

Answer:

1) In order to fill 2/3 of the vase, you would need 72$\pi$ of water.

Step-by-step explanation:

In order to find this, use the volume formula for a cylinder.

V = $\pi$r^2h

Now input the data

V = $\pi$(3)^2(12)

V = $\pi$(9)(12)

V = 108$\pi$

Now since we have the volume of the whole thing, we can multiply by 2/3 to get 2/3 of the overall volume.

V = 108$\pi$ * 2/3

V = 72$\pi$
