What is Semicircle Radius Calculation Problem about?

The document describes a math problem where the painted area of a semicircle is 2/5 of the whole semicircle. The task is to find the radius of the smallest possible semicircle given this information. It provides the equation [(10)^2 x 3]/2 = [{ r^2 + (10 – r)^2 } x 5]/2 to solve the problem, and shows the steps of inserting numbers into the equation and solving for r to find the radius is 5+√5.
