Breaking Down the Problem: How to Calculate the Area Ratio Safely
To understand the ratio of the circle’s area to the triangle’s area, begin with known values: hypotenuse $ c = 10 $ cm, inradius $ r = 2 $ cm. For any right triangle, the radius $ r $ of the inscribed circle is given by $ r = \frac{a + b - c}{2} $, where $ a $ and $ b $ are the legs. Rearranging with $ c = 10 $, we solve $ 2 = \frac{a + b - 10}{2} $, leading to $ a + b = 14 $. Using the Pythagorean theorem $ a^2 + b^2 = 100 $, we form a system that lets us solve for $ a $ and $ b $. Upon solving, values converge near $ a = 6 $ cm and $ b = 8 $ cm—consistent with the well-known 6-8-10 Pythagorean triple scaled slightly. The triangle’s area is $ \frac{1}{2}ab = \frac{
