Explanation:
Answer:
The cylindrical tube can hold 0.215 cubic decimeters of blood.
Explanation:
Diameter of the cylindrical tube = d = 4.5 cm
r = d/2 ,r = 2.25 cm
Height of the cylindrical tube = h = 13.5 cm
Volume of the cylinder = V = 



The cylindrical tube can hold 0.215 cubic decimeters of blood.
An ionic compound is made up of two or more metals and non-metals
A covalent compound is made up of two or more non-metals.
Therefore calcium (non-metal) and chlorine(non-metal) make up a covalent compound
