   Tom and Steve are enjoying a holiday camp with their football club. Today it's their task to prepare the meal for all the members of the club.

   

   They have a large cooking pot with an inner diameter of 30 cm and a height of 40 cm.

   Can they get 20 litres in it, if they fill it up to 10 cm under the brim?
