Birthday Cake

CodeChefOpen on judge ↗

It's the 20th birthday of your best friend Abir and it's the time to give him a massive surprise. As a part of the surprise, you have decided to order 2 big cakes (as he is foodie)! But there arises a little problem. The cakes are circular in shape and you want to pick a box (yeah, it is also circular in shape) in which the cakes will be fitted perfectly. You're given the diameters of two cakes.
