A glass is shaped like a right circular cylinder with a half sphere at the bottom. The glass is 7 cm deep and has a diameter of 6 cm, measured on the inside. If the glass is filled to the rim with apple cider, how much cider is in the glass? The formula to the volume a sphere is 4/3*Ï€*r^3.

$$A.\ 18\pi$$
$$B.\ 36\pi$$
$$C.\ 54\pi$$
$$D.\ 81\pi$$
$$E.\ 108\pi$$

The OA is C.

I'm confusing about the part "If the glass is filled to the rim with apple cider..." , how do we understand this PS question? I appreciate if any expert explain it for me. Thank you so much.
