Question

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

Answer 1

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
