help on equations of a wine glass
i have an assignment to do the wine glass for maths and i dont know any equation. it has a table with colums that say ; glass part (eg. base, stem and body), function, domain and coordinates in mm.
it should have at least 6 functions please help and i dont want a glass that is too complecated.

The simplest wine glass structure to use would have a cylindrical base, a cylindrical stem, and a half-sphere body.
Give the following dimensions of the wine glass:
radius of base, height of base, radius of stem, height of stem, and radius of body
Provide the following equations for surface area:
SA of cylindrical base = 2 * pi * r^2 + 2 * pi * r * h
SA of cylindrical stem = 2 * pi * r^2 + 2 * pi * r * h
SA of half-sphere body = (4 * pi * r^2) / 2
To find the total surface area of the wine glass, add the three answers above.
Next, provide the following equations for volume:
V of cylindrical base = pi * r^2 * h
V of cylindrical stem = pi * r^2 * h
V of half-sphere body = (4/3 * pi * r^3) / 2
To find the total volume of the wine glass, add the three answers above.
So here is how I would phrase the question.
A wine glass has a cylindrical base, a cylindrical stem, and a half-sphere body. The base has a height of __ mm and a radius of __ mm. The stem has a height of __ mm and a radius of __. The body has a radius of __ mm. Use this information to find the total surface area and the total volume of the wine glass.
