The correct interpretation of the end behavior in the context of the equation \( V = 43\pi r^3 \) is:
As the radius increases to infinity, the volume of the sphere will increase to infinity.
This is because the volume \( V \) depends on the cube of the radius \( r \), and as \( r \) increases, \( r^3 \) also increases, causing the volume \( V \) to increase accordingly. The other statements are not accurate representations of the relationship.
