Is it possible to define the area of a circle using math.rad, or radians? Not create a circle out of bricks like on the wiki. I mean defining an area, like get all parts within the area of said circle. If I wanted to get every part within a radius of another part, how would I do it? Can I do it?
I'm sorry if this isn't very clear, its the best I could do to describe what I have in mind.

More info needed. Define the area of a circle? What does that mean? Spell it out for us, we aren't going to guess at it.
Added more detail to the question. Hopefully it makes more sense now. Thanks.
You want to get a list of parts that are in a sphere? Within a particular distance to an object?
Bingo, but more like a cylinder. What I want to know is how I could achieve that through the use of math, or any existing Roblox methods. (I forgot 'Cylinder' was a word at the time of asking the question, whoops XD)
