Find 3/4 of the height:
Height = 10 inches
3/4 of the height = 3/4 x 10 = 7.5 inches
Find the amount of water she should fill:
Volume = πr²h
Volume = π(4)²(7.5) = 377.14 in³
Answer: Mary should pour in 377.14 in³ of water.

Step-by-step explanation:
Volume of vase = πr^2h
=22/7 × (4in)^2 × 6in
=22/7 × 16 in^2 × 6 in
=2112/7 in^3
4/5 of 2112/7 in^3=8448/35 in^3
Therefore, Mary should fill the vase with 3.95537 l of water.
