Excelente explicación gracias por su tiempo y dedicación. From Bogota D.C

Nice one after long gap. Many thanks Madam!

Found the formula in the back of my copy Major-General Shortrede’s logarithmic Trig Function Tables (19th century). Didn’t know it’s called Heron’s formula. Shortrede uses it thus: SinA=(2/b*c)*area.

Heron's formula is one for the book for future reference, thank you!

Amazing solution, keep it up!

Ingenious...

Hmm. so the answer turns out to be the triangle's area divided by S (the semi-perimeter of the triangle). Is it always that way? Because then we could solve for the radius in just a few seconds each time.

Exact form: r = (√231)/6

Like √8*9*10/ 6 ?

How do you get 231 and 6?

I got the same answer 😅

Very good!

this is the first time i heard about that heron's formula. This algorithm is good for finding the maximum radius of a circle in a given triangle. I think. But square root in programming is quite slow.

for anyone interested to implemented this in code, you can find r by: r=2*total_triangle_area/|AC|+|AB|+|BC|

Tnx!❤

Is there any shorter method?

I mean it's not hard and I can easily do it but it's too lengthy

After finding area of triangle using heron’s equation, you can use a simple equation: area of triangle equal to semi perimeter times radius.

​@@drwzerThat’s what GPT4 does.
