what would be the radius of a circle that can be inscribed in a triangle with sides of 35, 29 and 64?

Here is a formula in terms of the three sides:
If the sides have length a, b, c, we define the semiperimeter s to be half their sum, so s = (a+b+c)/2. Given this, the radius is given using the following:
rHere is a formula in terms of the three sides:
If the sides have length a, b, c, we define the semiperimeter s to be half their sum, so s = (a+b+c)/2. Given this, the radius is given using the following:
r² = (s  a)*(s  b)*(s  c) / s
