then please, explane a radius. thats part of a circle. and it has two points. or better yet, a diameter. how does one find the dimensions of a circle? gee... pie times the raidus.... squared i think.... yes, it's squared. and becuase you use it, it is part of it. keep trying though, your attempt shows how long you've been out of school.

Pi * r² (pi times radius squared) or pi * d (pi times diameter)

Depends if you are looking for area or diameter. Once you understand Dimensional Analysis you will never get them confused again. Now it gets a bit tougher (not much :-)) if you are looking for the area of a paraboloid or hyperboloid like what I use in my work.

Dollars to donuts, this kid doesn't even have a clue what the word stochastic means.

The radius is not part of the circle. You should learn some elementary geometry. Be careful not to confuse a circle with a disk.
