Knowing the arc length and chord length, how to find the arch height?

I hope the expert can provide specific steps; it would be even better if there’s an Excel file format! ! !
I found the formula in the hardware manual, but I still can’t calculate it correctly!

Let the length of the chord be L, the length of the arc be C, and the radius be r. Then the relationship between the chord and the arc length is: C = arcsin(L/2r)×2r ...................... in radians; C = arcsin(L/2r)×πr/90 .............. in degrees. The radius can be calculated once that is known, and then everything else is straightforward
