What is the Formula for the Inradius ?

Solution :

Inradius Formula (r) = \(\Delta\over s\)inradius

Where r = radius of the circle inscribed in a given triangle

\(\Delta\) = area of the given triangle

\(\Delta\) = \(\sqrt{s(s – a)(s – b)(s – c)}\)

s = half perimeter of the given triangle

s = \(a + b + c\over 2\)  for all a, b c are the sides of a given triangle.
