Help with spheres

My thanks to everybody. This helped a lot. If you will excuse the expression, We're rolling!

Yeah, we are really on the ball aren't we?

All we have to fear is sphere itself.

We are such a well rounded bunch, it doesn't surprise me that we could help.

How about figuring out how much chopped walnuts you need for a cheese ball? Mandatory hotlink:

No idea how this is relevant but I need to put this pic somewhere.

as far as I'm concerned ... here in NC if you're at my house .... no coverage is required.... (yes I realize that can be taken 2 ways )

Coatings of any type (in cars, swain coatings on a hemispherical combustion chamber seems to fit the question)....

Area of the end caps of a tubular tank (spherical ends) so that painters can get an idea of the amount of material to cover it...

Calculating the thermodynamics of heating and cooling in a spherical container are much easier with surface area sizes...

Actually, if you wanted to figure out any heat transfer to or from the sphere it would be a necessity to know the surface area.
