Calculus Optimization Problem - Minimize area of shapes created by cutting a 20 cm wire

In this video I solve a pretty unique calculus optimization problem requested by a subscriber. The problem reads: A wire of length 20 cm is cut into 2 pieces which are then bent into the shape of a circle of radius r and equilateral triangle with side length s. Find the value of r which minimizes the total area enclosed by the circle and the triangle. Keep those questions coming in and if this is your request, I hope you find it helpful!
