In order to cut the next circle on the iron sheet of a right triangle, ab = 60cm and BC = 80cm are known In order to make full use of this piece of iron, the diameter of the cut disc should be as large as possible How to cut? What is the maximum diameter of this circle?

Let the diameter be X
60x/4+80x/4+100x/4=80*60/2
x=40
