I have to find the area, but the derivative of the area is the circumference anyways, so w/e. I'm attempting to find it, and I got 0=2pi (sqrt w^4+40000) / 4x^2. It's...impossible to solve for w O_o.
.
Also here: 2*pi*(sqrt( (a/2)^2 + (200/b/2)^2 ) and here: (sqrt ((a/2)^2+b/2^2)) = r. Isn't there supposed to be a b/2? Why is that left out to find the radius?
