1 - this is not homework.
2 - I havent thought about this stuff since high school and that was approx. 30 years ago.
I have a problem that I would like to solve - not numerically, but in simplification.
Problem - find area of a circle with a given radius. I know the area formula is A=PI(r)^2. The radius is: 1/(2 * sqrt (PI)). the overall formula is:
A = PI * (1/(2 * sqrt(PI) ) )^2
Since the radius portion is squared, I recall that it can be simplified, but dont recall the rules for doing so. I am not looking for a final answer for A, just how to simplify the r^2 portion.
Note: ^ = raised to the power, sqrt - square root
