Karla takes a bath in a perfectly circular pool. She likes it very much since she is right in the middle of the pool. At the edge of the pool are balls - red, green and blue. The red and green balls are apart, the red and blue are apart, and the last two are apart. There is also a naughty frog at the edge of the pool. What is the shortest distance between Karla and the frog?
