This question is based upon the (incorrect) idea that all 3 of these bottles are uniformly-shaped cylinders. But I'd suggest you accept that convention.
The volume of a right circular cylinder is V = (base)(height), where the (base) is the base area: A=pi * r^2, where pi is taken to be 3.14.
Last case: the radius is 6 cm and the height is 32 cm. The area of the base is then 3.14 * 6^2 cm^2 (simplify this), and the height is 32 cm. Multiply these together to obtain the volume of the bottle. Be certain to include the unit of measurement, cm^3.
