A 'partial cone' probably means a truncated cone or frustum (See Related Link).
The easiest way to calculate a surface area of a partial cone is to assume the cone is full. We will call this cone #1. Now, calculate the surface area of a cone and assume the base is equal to the top base of your partial cone. We will call this #2.
Now you have two cones. If you subtract cone #2 from cone #1 you will get your desired cone.
For a detailed answer:
SA= pi * (R + r) * [ ( R - r )2 + h2 ]0.5
where:
h=height of frustum
R=Base Radius (bottom base)
r=top base Radius
( R > r )
This assumes that the flat surfaces are parallel.

No, the formula is far from simple - requiring elliptical integrals.
it stands for the total surface area
The surface area of a right cone is the amount of square units that is needed to cover the surface of a cone. To find a surface area of a right cone , follow this formula S.A = 3.14rl + 3.14r(r) I hope it helped you.
The curved surface area of a cone is: pi*radius*slant length.
Surface Area = Pi*radius(radius + slant height)
