Answer:
4.7 feet³ of water
Step-by-step explanation:
Diameter of 4 feet
Radius = 2 feet
Height = 0.75 feet
Formula for Volume = 2· ·radius·height
·radius·height
But she only wants to fill half, so divide by 2, cancels the 2 in the formula for volume, giving us:  ·radius·height
·radius·height
 ·2·0.75 = 4.71 feet³
·2·0.75 = 4.71 feet³
