given:
the diameter of its ends are: and and the thickness is

A=pi(a^2+b^2+2Rh)
is the radius of the smaller base->
is the radius of the larger base->
is the radius of the sphere
is the difference in height of the two base->

As we can see, we first have to determine the radius of the sphere . We can find the radius from the given base diameters and frustum height.






then the area is:
