Question
A triangle with sides of lengths 3 in., 4 in., and 5 in. has an area of 6 in $^{2}$. What is the length of the radius of the inscribed circle?
Step 1
The formula for the radius of the inscribed circle in a triangle is given by the formula $r = \frac{A}{s}$, where $A$ is the area of the triangle and $s$ is the semi-perimeter of the triangle. Show more…
