Find the total volume

Answer:
My calculation might be wrong, so take A.
Step-by-step explanation:
Volume= Volume of hemisphere+volume of cone
Volume= [tex]\frac{2}{3}[/tex]×π×r³ + πr²[tex]\frac{h}{3}[/tex]
Volume= [tex]\frac{2}{3}[/tex]×[tex]\frac{22}{7}[/tex]×4×4×4 + [tex]\frac{22}{7}[/tex]×4×4×[tex]\frac{14}{3}[/tex]
Volume= 134.095 + 410.6
Volume= 544.695
