Answer:
Volume of medication in the cup = 50.24 cubic inches
Step-by-step explanation:
Volume of the cylindrical cup = πr^2h
Radius, r = 2 inches
Height, h = 8 inches
Volume of the cylindrical cup = πr^2h
= 3.14 × 2^2 × 8
= 3.14 × 4 × 8
= 100.48
Volume of the cylindrical cup = 100.48 cubic inches
If David only fills the cup half way,
then, the volume of medication in the cup = Total volume of the cylinder / 2
= 100.48 inches / 2
= 50.24 cubic inches
volume of medication in the cup = 50.24 cubic inches
