Answer:
7776[tex]\pi[/tex]
Step-by-step explanation:
Sphere Volume Formula = 4/3 times [tex]\pi[/tex] times r^2
r is the radius and in this case its 18.
4/3 times [tex]\pi[/tex] times 18^3
4/3 times 5832 times [tex]\pi[/tex]
4 times 1944 times [tex]\pi[/tex]
7776 times [tex]\pi[/tex]
The volume of the sphere is 7776[tex]\pi[/tex]
