radius = 9 and 4.5

Sphere Volume   =   4/3 • π • r³

Entire Outer Volume = 4/3 • 3.14 • 9^3

Entire Outer Volume = 4/3 • 3.14 • 729

Entire Outer Volume =



3,052.08



cc

Inner Core Volume = 4/3 • 3.14 • 4.5^3

Inner Core Volume =



381.51



cc

Outer Layer Volume = (

3,052.08


-381.51) =



2,670.57

cc
