Hard/Unsolved Help with puzzle needed
I couldn't solve it. AI says that puzzle has 1 solution. But i couldn't find it

Hi everyone!
Because of the influx of unsolvable, annoying, arbitrary, and spammy posts, I’ve established a few rules for posts. Basically, we are no longer allowing “math puzzles” that rely on sequences of numbers or shapes. There is an infinite number of solutions and they’re plain not fun.
Also, I put in a rule about not linking to other games. Puzzles posted here should be contained in the post itself.
Have a great weekend!

Trace a path through the wheel: number, operator, number, operator, … ending on a number.
You can jump from any tile to any tile, but each tile can be used only once (or not used at all).
One rule to keep in mind: the path is calculated left to right, like a basic pocket calculator. So if you trace:
2 → + → 3 → × → 5
it evaluates as (2 + 3) × 5 = 25.
Targets to solve: 19, 44, 63, 100, 144. The video solves 19 with path 7 → × → 2 → + → 5. Find a path for each of the other four.

In situation A we have a rectangle with side lengths a and b. According to the figure, b / a = 0.60. The circles are identical and have the maximum possible diameter, d, so they do not extend beyond the confines of the rectangle.
In situation B, the height of the rectangle has increased slightly to c, thus allowing the circles to be larger: The diameter of the circles have increased from d to e.
Question: Let b/a = 0.60 and c/a = 0.50. What is the ratio of the diameters of the circles in situation A and B, e/d ?
