V=∏r^2h

V=∏(1.5^2)(4)

V=∏(2.25)(4)

V=∏(9) for the cup

for the pot the height does not matter, so let the height be 5 inches (or whatever height you like)

V=∏(4^2)(5)

V=∏(16)(5)

V=∏(80) for the pot

V=80∏-9∏

V=71∏ left in the cup

now find the height of the pot and compare it with the original height

71∏=∏(4^2)h

71∏=16∏h

divide both sides by ∏

71=16h

h=71/16

h=4 7/16 inches

the original height was 5 inches

5-4 7/16=9/16 of an inch

the level went down 9/16 of an inch in the pot
