a piece of wire 10m long is cut in 2 portions. once piece is bent to form a circle, other a square. find the circumference of the circle if the sum of the areas is to be a minimum. give your answer in terms of pi.

differentiate y= x/sqrt(x^2+1)

intro calculus question please help with working out :)
