Correct C. 936π ft³

Step-by-step explanation:

The formula for the volume of a sphere is:

V = 4/3 r³ π

Let the radius of the first sphere be r₁ = 3 ft and the second r₂ = 9 ft

Increasing the volume of the sphere is equals to the difference of V₂ and V₁

ΔV = V₂ - V₁ = 4/3 r₂³ π - 4/3 r₁³ π = 4/3 π ( r₂³ - r₁³ ) = 4/3 π ( 9³ - 3³ )

ΔV = 4/3 π ( 729 - 27 ) = 4/3 π · 702 = 4 · 234 · π = 936 π ft³

ΔV = 936 π ft³

God is with you!!!
