Exterior angles
That is called the area.
If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.
It is the surface area of the solid.
If the shape is circle then circumference. If any other form (non-symmetrical) then you can measure the area with integration from Calculus.
